Labour market statistics measure many different aspects of work and jobs and provide an insight into the economy. They are also very much about people, including their participation in the labour force, the types of work they do, the earnings and benefits they receive and their working patterns. The Office for National Statistics (ONS) has developed a framework for labour market statistics to describe the major concepts that exist within the labour market and their relationship to each other. The framework is based on the concepts of labour supply and demand. This approach has wide international acceptance, including by the International Labour Organisation (ILO). Labour supply consists of people who are employed, as well as those people defined as unemployed or economically inactive, who can be considered to be potential labour supply. The ONS framework distinguishes between these three categories of worker, and also between the different working arrangements of those in employment such as, employees, the self-employed and those on government schemes. Labour demand is represented by employers, who have a need for work to be done, and who offer compensation for this work to the employees who undertake it. This work is grouped by employers to form jobs. Users of labour market statistics include central and local government, economists, financial analysts, journalists, businesses, trade unions, employer associations, students, teachers, industrial tribunals, academic researchers and lobby groups. They use them for the analysis, evaluation, monitoring and planning of the labour market and economy. Labour market statistics are also used for social analysis and help inform a wide range of government policies towards population groups of particular concern (women, young people, older people and jobless households).
Estimates of earnings and pay generally cover three main areas: basic pay, overtime and bonuses. Earnings exclude non-standard ways of being paid as a member of staff (for example, share offers in the company, benefits in kind, and compensation for expenses incurred for travelling and subsistence while carrying out the employer's business).
Earnings statistics can be classified into two categories:
structural statistics, and
Structural statistics tend to be more detailed and are used to analyse trends in earnings over long periods. The Annual Survey of Hours and Earnings (ASHE), and before it the New Earnings Survey, is the recommended source of employees' pay level. Data are published on an annual basis for the UK, and also broken down by industry, occupation, region, small area, gender and full-time/part-time status. ASHE data are published annually in November, using data from the previous April. AWE estimates appear monthly in the Labour Market Statistics Releases.
For estimates of short-term pay or earnings growth, the Average Weekly Earnings (AWE) (184.4 Kb Pdf) statistic is the source recommended by the Office for National Statistics (ONS), providing estimates of monthly and annual change for the main industrial sectors.
Average Weekly Earnings was accredited a National Statistic in November 2009, and replaced the Average Earnings Index (AEI) as the lead measure of short-term earnings growth in January 2010. It measures the changes in average weekly earnings of employees. The AWE is based solely on the Monthly Wages and Salary Survey (MWSS), which covers employees working in businesses with 20 or more employees in all industrial sectors in Great Britain (an adjustment is made for smaller businesses).
As well as tracking changes in earnings, AWE makes an explicit estimate of earnings in pounds. Separate estimates are made of bonus and arrears pay. AWE uses employment weights that are recalculated every month. This means that AWE reflects the composition of the workforce at any given time, and that changes between months capture shifts in the workforce as well as changes in earnings within industries. These are both advantages over the former AEI measure, and two of the main reasons for the switch between the measures.
AWE is used to produce figures for the economy as a whole, and by sector and industry. The AWE uses the number of employees on an employer's payroll as its denominator, so changes in the number of paid hours worked (assuming the pay rate per hour stays the same) will show as an increase or decrease in average earnings as appropriate.
The Average Earnings Index (AEI) was a well-established National Statistic, which until January 2010 was the lead measure of short-term earnings growth. It has now been replaced by the Average Weekly Earnings (AWE) measure.
In terms of structural statistics, the Annual Survey of Hours and Earnings (ASHE) (189.4 Kb Pdf) is the main measure. ASHE measures the average level and distribution of earnings and paid hours for employee jobs. Estimates are presented by a number of breakdowns including gender, occupation, industry and region.
The survey is a sample survey of employee jobs, although information is collected from employers. It is based on a one per cent random sample of jobs on the HM Revenue and Customs Pay As You Earn (HMRC PAYE) register. It covers all employee jobs in all industries and occupations across the whole of the UK. It has a reference date in April, asking about individuals who are employees at that time. This reference date changes each year depending on when Easter falls.
The Index of Labour Costs per Hour (ILCH) (273.2 Kb Pdf) is published quarterly and is available for both the UK and Great Britain. This is also an experimental statistic, developed to meet the European Union Regulation EC 450/2003.
It is a more widely defined measure than AWE, going beyond wages and salaries to include non-wage costs such as employer National Insurance and pension contributions, sickness, maternity and paternity payments and benefits in kind, that are not considered by the other indicators. However, in terms of movements in the index, the inclusion of non-wage costs has a relatively small impact since they account for a small and relatively stable proportion of total pay.
The main difference in movements between the ILCH and the AWE is that the ILCH gives estimates per hour actually worked, whereas the AWE gives earnings per employee.
The number of people in employment in the UK is measured by the Labour Force Survey (LFS) and consists of people aged 16 and over who did paid work (as an employee or self-employed), those who had a job that they were temporarily away from, those on government-supported training and employment programmes, and those doing unpaid family work. Employment levels and rates are published each month in the Labour Market Statistical Bulletin.
Employment is a different, but similar concept, to jobs. Employment is a measure of people and a person with more than one job would therefore be counted once in the employment estimates. The LFS provides the best measure of employment at whole economy level as it is a more comprehensive measure than jobs. However the jobs estimates provide a more reliable industrial breakdown than the LFS because it is mainly sourced from employer surveys which provide a more reliable industrial breakdown than household surveys.
Estimates are available by sex, by age and for full-time, part-time and temporary workers. Employment levels measure the total number of people estimated to be in employment while employment rates allow changes in the labour market to be interpreted in a wider context by allowing for changes in the population. The headline measure of employment for the UK is the employment rate for those aged 16 to 64.
Estimates of employment are also available for former Government Office Regions (GORs) and at local area level. Regional estimates of total employment are measured by the LFS while more disaggregated regional employment estimates and local area estimates are measured by the Annual Population Survey (APS).
Estimates of total employment levels and rates for the UK are available from 1971. Most other employment estimates are available from 1992. The concept of employment lies on the supply side of the labour market framework, as it measures those people who supply their labour.
Employees are those who are in employment and paid a wage by an employer for the work that they do. This category may be further sub-divided into permanent and temporary employees.
Self-employed are those people who regard themselves as self-employed, that is, who in their main employment work on their own account, whether or not they have employees.
Unpaid family workers are those who work in a family business who do not receive a formal wage or salary but benefit from the profits of that business.
People on government supported training programmes are classified as in employment if they are engaging in any form of work, work experience or work-related training. However if they are not engaging in any form of work, work experience or work-related training, they are NOT classified as being in employment; such people are classified as unemployed or economically inactive.
Temporary workers are those employees who say that their main job is not permanent in one of the following ways: fixed period contract, agency temping, casual work, seasonal work or other temporary work. This is also based on respondents' self-assessment.
Employment is classified by occupation and industry. The LFS also allows analysis of the personal characteristics of those in employment such as their sex, age, ethnic group and highest qualification.
Public sector employment comprises employment in central government, local government and public corporations as defined for the UK National Accounts. Data are collected from public sector organisations from the Quarterly Public Sector Employment Survey (115.9 Kb Pdf) and other sources. Employment estimates for the private sector are derived as the difference between employment estimates for the whole economy, derived from the Labour Force Survey, and the public sector employment estimates. There is a Brief Guide to Sources of Public Sector Employment Statistics (47.5 Kb Pdf) available on the website.
Private sector employment is estimated as the difference between total employment, sourced from the Labour Force Survey, and public sector employment.
Comparisons of public and private sector employment since 2008 are complicated by a number of changes to the composition of the public and private sectors with several large employers moving between these sectors. These major reclassifications are as follows:
Royal Bank of Scotland is included in the public sector from December 2008 but in the private sector for earlier time periods.
Lloyds Banking Group plc is included in the public sector from December 2008 to December 2013, but in the private sector for earlier and later time periods.
Direct Line Group is included in the public sector from December 2008 to June 2013, but in the private sector for earlier and later time periods.
Further education corporations and Sixth Form College Corporations in England are included in the private sector from June 2012 but in the public sector for earlier time periods.
Royal Mail plc is included in the private sector from December 2013 but in the public sector for earlier time periods.
As well as estimates of total public and private sector employment, ONS also publishes estimates excluding major reclassifications, which show the underlying movements in public and private sector employment.
Estimates of weekly hours of work, including paid and unpaid hours, for the UK are measured by the Labour Force Survey (LFS).
Actual hours worke d statistics measure how many hours were actually worked. These statistics are affected directly by changes in the number of people in employment and in the number of hours that people work. The figures are seasonally adjusted to take account of calendar-related absences from work during the reference period such as public holidays and time off work for school holidays. The figures are also affected by other absences from work such as those due to sickness.
Average hours worked measure the average number of hours worked per week for all workers, for full-time workers, for part-time workers and for workers in second jobs.
Usual hours worked measure how many hours people usually work per week. Compared with actual hours worked, they are not affected by absences and so can provide a better measure of normal working patterns. Estimates of hours worked are published each month in the Labour Market Statistical Bulletin. When conducting analysis of hours, there are three main elements to consider:
whether to use usual or actual hours worked
whether to include paid and unpaid overtime
whether to include hours worked in further jobs
Estimates of total actual hours worked for the UK are available from 1971. Other hours worked estimates are available from 1992. Estimates are available by sex and also for former Government Office Regions (GORs). Regional estimates of hours worked are measured by the Annual Population Survey (APS). Estimates of paid hours worked are measured by the Annual Survey of Hours and Earnings (ASHE).
Productivity measures are essential in assessing the efficiency, competitiveness and underlying ‘potential’ rate of growth of an economy. The Office for National Statistics (ONS) headline productivity measure is output per worker, but other key published productivity measures are output per filled job, output per hour worked and unit labour costs. The first three of these measures are based on the amount of real (inflation adjusted) economic output per unit of labour input, while unit labour costs are based on the labour cost of producing a unit of output.
Productivity measures are published for the whole economy, the manufacturing and production sectors, the service sector, and more detailed industrial sector level, notably for manufacturing. Market sector productivity is also published.
Productivity indicators are also published at the regional level and in comparison with other countries. ONS also publish experimental series and related articles on multifactor productivity, and the necessary components of capital services and quality adjusted labour input (QALI).
UK productivity series are calculated using:
Gross Value Added (GVA) from the National Accounts
worker, jobs and hours data from the Labour Force Survey (LFS), and
Reporting Unit (RU) based employee jobs data at industry level from the Workforce Jobs estimates (WFJ) constrained to LFS total employee jobs
Nominal regional productivity estimates are produced annually, and are at the former Government Office Region level. They are published in the Labour Productivity Statistical Bulletin once a year.
International Comparisons of Productivity (ICP) in current and constant prices are produced and published by ONS, but are based on OECD macroeconomic data and Eurostat and OECD Purchasing Power Parities (a form of exchange rate), which are used to convert international data to a consistent basis. ONS base the current price comparisons around the UK, so that other counties’ productivity levels in relation to the UK equal 100. Constant price productivity is indexed to a common year for all countries and the G7 aggregate.
The Labour Disputes Inquiry (124.3 Kb Pdf) collects information on the number of working days lost and workers involved in strike action in the UK on a monthly basis. The survey is different to most other business surveys conducted by the Office for National Statistics (ONS) in that it is conducted on a voluntary basis and is a list of all known strikes in the period.
The survey tries to record all strike action that has taken place, except for those disputes involving fewer than ten workers or lasting less than one day. Disputes are picked up from reports in the mainstream media and newspapers, with news and union websites also being a primary source of information. Where possible, the data are collected directly from the employer involved in the dispute. There are also centralised returns from large companies, public bodies and trade unions.
The Labour Disputes Survey collects data on the number of working days lost and the number of workers involved in strike action from all UK companies who have been involved in strike action. However, lack of press coverage generally means that small disputes are not always included.
Data from the Labour Disputes Survey are used by a wide range of users, both internal and external customers. The figures are used by the Department of Business, Innovation and Skills (BIS) to provide ministers with a monthly brief on labour disputes and also by HM Treasury and the Advisory, Conciliation and Arbitration Service (ACAS).
Outside government, the data attract interest from researchers, local authorities, development corporations, academics and private industry. In accordance with the International Labour Organisation (ILO) 'Resolution on Strikes and Lockouts: 1993', the UK provides the ILO with data covering working days lost, number of workers involved and the number of stoppages by industry for each calendar year.
The Labour Disputes Survey, on a voluntary basis, requests the minimum amount of detail to produce the analyses required by users. The overwhelming majority of firms rarely experience labour disputes stoppages and consequently do not have formal mechanisms for recording the data.
Information is not available on the completeness of coverage so, consequently, it is not known what proportion of all stoppages are included in the statistics. Data are not collected for those disputes involving fewer that 10 workers or lasting less than half a day. However, data are collected if 100 working days are lost due to a single dispute, regardless of the amount of workers involved.
The Labour Disputes Monthly Provisional Results are published six weeks after the reference period and the previous period’s data are revised if necessary. A further (final) revision is also conducted when the annual results are published in March if additional data have been made available. Revisions are generally very small.
The time lag between publication and the reference period to which the data refer are as follows:
monthly results release: six weeks after the reference period
annual results release: 12 weeks after the reference period
annual in-depth analysis: six months after the reference period
Data on UK labour disputes are held going back as far as 1891. Analysis can be provided on various combinations, for example, by industry groups, by Standard Statistical Region from 1958 to 1995, by former Government Office Region (GOR) from 1996 and by cause (from 1959). Data are also published on a public/private split, with data available back to 1996.
The number of economically inactive people in the UK is measured by the Labour Force Survey (LFS) and consists of people aged 16 and over without a job who have not sought work in the last four weeks and/or are not available to start work in the next two weeks. The main economically inactive groups are students, people looking after family and home, long term sick and disabled, temporarily sick and disabled, retired people and discouraged workers.
The headline measure of inactivity for the UK is the inactivity rate for those aged from 16 to 64. Estimates of inactivity are also available for former Government Office Regions (GORs) and at local area level. Regional estimates of total inactivity are measured by the Labour Force Survey (LFS) while more disaggregated regional inactivity estimates and local area estimates are measured by the Annual Population Survey (APS).
The characteristics of people who are economically inactive vary depending on their reason for inactivity. For example, students tend to be young and at the start of their working lives. Those looking after the family and home tend to be female and of child rearing age and retirees tend to be close to retirement age.
Inactivity levels and rates are published each month in the Labour Market Statistical Bulletin. Estimates are available by sex, by age and by reason for inactivity. Inactivity levels measure the total number of people estimated to be economically inactive while inactivity rates allow changes in the labour market to be interpreted in a wider context by allowing for changes in the population.
Estimates of inactivity levels and rates for the UK are available from 1971. Most other inactivity estimates are available from 1993.
Redundancies are measured by the Labour Force Survey (LFS). The estimates measure the number of people, whether working or not working, who reported that they had been made redundant or had taken voluntary redundancy in the month of the reference week or in the two calendar months prior to this.
Redundancy levels and rates are published each month in the UK Labour Market Statistical Bulletin. The redundancy rate is based on the ratio of the redundancy level for the given three-month average time period to the number of employees in the previous quarter.
Estimates of redundancy levels and rates for the UK are available seasonally adjusted by sex, for rolling three-monthly average time periods.
More detailed estimates of redundancies (by region, industry, age and re-employment rates) are available not seasonally adjusted and for calendar quarters. Redundancies estimates are not available at local area level. Estimates of redundancy levels and rates for the UK are available from 1995, but more detailed estimates are not available prior to 1997.
The Claimant Count measures the number of people claiming benefits principally for the reason of being unemployed. Since October 1996 it has been a count of the number of people claiming Jobseeker’s allowance. The headline Claimant Count does not yet include people claiming Universal Credit - a new benefit which has so far only been introduced in a small number of Jobcentre Plus offices (see below for further details). The Claimant Count does not meet the internationally agreed definition of unemployment specified by the International Labour Organisation (ILO). The estimates are sourced from the JobCentre Plus administrative system.
The Claimant Count includes people who claim Jobseeker’s Allowance but who do not receive payment. For example some claimants will have had their benefits stopped for a limited period of time by Jobcentre Plus; this is known as “sanctioning”. Some people claim Jobseeker’s Allowance in order to receive National Insurance Credits.
The count of claimants of unemployment related benefits, which is known as the Claimant Count, is based on the administrative records of people claiming these benefits. Since October 1996, this has been the number of people claiming Jobseeker's Allowance (JSA). The Claimant Count consists of all people claiming JSA at Jobcentre Plus local offices. They must declare that they are out of work, capable of, available for and actively seeking work during the week in which their claim is made.
As well as numbers of people claiming benefits, estimates are also available for Claimant Count rates and proportions. Claimant Count rates for the UK and at Government Office Region (GOR) level are calculated as the Claimant Count level divided by the sum of the Claimant Count plus the total number of jobs. Claimant Count proportions are available at local area level. These are calculated as the number of claimants resident in an area as a percentage of the working-age population of that area.
Claimant Count estimates for the UK are available seasonally adjusted by sex, age and duration of claim. This level of detail is also available not seasonally adjusted for GORs. Estimates for the total Claimant Count not seasonally adjusted are available at local area level. Claimant Count estimates are available from 1971. Claimant Count levels and rates are published each month in the Labour Market Statistical Bulletin and on the NOMIS ® website.
People who qualify for JSA through their National Insurance contributions are eligible for a personal allowance for a maximum of six months. This is contribution-based JSA. People who do not qualify for contribution-based JSA can claim a means-tested allowance. This is income-based JSA. Those claiming JSA enter into a Jobseeker’s agreement. This sets out the action they will take to find work and to improve their prospects of finding employment.
The seasonally adjusted Claimant Count series, which goes back to 1971 for the UK, is estimated on a basis consistent with the current benefits regime, that is, it has been adjusted for discontinuities in coverage. The non-seasonally adjusted series includes all claimants aged 16 and over while the seasonally adjusted series includes all claimants aged 18 and over. This difference in coverage exists because restricting the seasonally adjusted series to those aged 18 and over was the only realistic way of maintaining the consistent series back to 1971, following a rule change in 1988 which resulted in most 16 to 17-year-olds becoming ineligible to claim unemployment-related benefits.
Claimant Count rates for the UK and for Government Office Regions (GORs) are calculated as the number of claimants who are resident in each area as a percentage of workforce jobs plus the claimant count. Workforce jobs are the sum of:
HM Armed Forces
The largest part, the employee jobs, represents jobs by the location of the employer. The estimate of workforce jobs therefore, tends to reflect the location of jobs rather than the residence of jobholders.
At local area level, comparisons are published in the form of the Claimant Count expressed as a proportion of the local resident population of working age. These proportions avoid distortions to rates, which would be caused by commuting patterns, if they were calculated as above for smaller areas.
There is a large degree of overlap between the Claimant Count and unemployment although the latter figures are generally higher. People who are not claimants can appear among the unemployed if they are not entitled to unemployment related benefits. For example:
people who are only looking for part-time work
young people under 18 are not usually eligible to claim JSA
students looking for vacation work
people who have left their job voluntarily
Some people recorded in the Claimant Count would not be counted as unemployed. For example, in certain circumstances people can claim Jobseeker’s Allowance while they have relatively low earnings from part-time work. These people would not be unemployed.
Estimates of inflows onto the claimant count and outflows from the count are published every month. To make comparisons over time consistent, these estimates are standardised to a 41/3 week month before seasonal adjustment. These estimates for people starting to or ceasing to claim Jobseeker's Allowance can be helpful towards interpreting changes in the claimant count.
The introduction of Universal Credit started on 29 April 2013 with the introduction of this new benefit in one Jobcentre Plus office (Ashton under Lyne). By December 2014 this has been extended to 91 Jobcentre Plus Offices. Further information for dates of roll out to UC can be found in List of Jobcentre Plus Offices under Universal Credit.
The Claimant Count measures the number of people claiming benefits principally for the reason of being unemployed. Following a consultation in 2012 by ONS, it was agreed that, with the introduction of Universal Credit, the Claimant Count would include:
• people claiming contribution-based JSA (which is not affected by the introduction of Universal Credit),
• people claiming means-tested JSA during the transition period while this benefit is being gradually phased out, and
• people claiming Universal Credit who are not earning and who are subject to a full set of labour market jobseeker requirements, that is required to be actively seeking work and available to start work.
Since July 2014, ONS has published two measures of the Claimant Count; the headline Claimant Count (which is a National Statistic) and a new experimental measure which, unlike the headline measure, includes some claimants of Universal Credit (UC). The experimental adjusted Claimant Count differs from the headline Claimant Count because, as well as JSA claimants, it also includes some claimants of Universal Credit (UC) from May 2013 (the first month in which the Claimant Count is affected by UC). Between May 2013 and October 2013, the UC estimates included in the adjusted Claimant Count include all claimants of UC including those who were in work. From November 2013 they include all out of work UC claimants but include some claimants who are not required to look for work (who should ideally be excluded from the Claimant Count).
ONS will, as soon as possible, include out of work and seeking work claimants of UC in the headline Claimant Count. The experimental measure will then be discontinued.
The number of unemployed people in the UK is measured by the Labour Force Survey (LFS) and includes people who meet the international definition of unemployment specified by the International Labour Organisation (ILO). This ILO definition defines unemployed people as being:
without a job, have been actively seeking work in the past four weeks and are available to start work in the next two weeks, or
out of work, have found a job and are waiting to start it in the next two weeks
This definition is used by most other countries, by the Statistical Office of the European Union (Eurostat), and by the Organisation for Economic Co-operation and Development.
Unemployment levels and rates are published each month in the Labour Market Statistical Bulletin. Estimates are available by sex, by age and by duration of unemployment.
Unemployment levels measure the total number of people estimated to be unemployed while unemployment rates allow changes in the labour market to be interpreted in a wider context by allowing for changes in the population. The headline measure of unemployment for the UK is the unemployment rate for those aged 16 and over. Unemployment rates are calculated, in accordance with international guidelines, as the number of unemployed people divided by the economically active population (those in employment plus those who are unemployed).
Estimates of unemployment are also available for former Government Office Regions (GORs) and at local area level. Regional estimates of total unemployment are measured by the Labour Force Survey (LFS) while more disaggregated regional unemployment estimates and local area estimates are measured by the Annual Population Survey (APS).
Estimates of total unemployment levels and rates for the UK are available from 1971. Most other unemployment estimates are available from 1992.
Unemployment data are useful for a variety of reasons. Government departments use unemployment estimates along with other labour market indicators for macro-economic and labour market management. Data are also supplied to a range of international organisations such as the European Central Bank. In the social policy domain, unemployment is used as an indicator of relative hardship.
Unemployment is different from the claimant count, which measures only those people who are claiming unemployment-related benefits (Jobseeker's Allowance since 1996). The claimant count is normally the lower measure because some unemployed people are not entitled to claim unemployment-related benefits, or choose not to do so.
The number of people with jobs is not the same as the number of jobs. This is because a person can have more than one job. The number of people with jobs is measured by the Labour Force Survey (LFS). The LFS also provides an estimate of the number of jobs by adding main and second jobs, but the industry breakdown is less reliable than that provided by Workforce Jobs (WFJ). Workforce Jobs (295.4 Kb Pdf) provides estimates of the number of jobs in the economy and is the preferred measure of short-term change in jobs by industry, but the employment estimates sourced from the LFS are the preferred measure of whole economy employment as the LFS provides a more comprehensive measure of employment.
WFJ is a compound measure and draws upon a range of sources:
employee jobs estimated from a range of employer surveys
self-employment jobs estimated from the Labour Force Survey (LFS)
HM Forces from administrative sources
Government-Supported Trainees (GST) from administrative sources
WFJ is published in the National and Regional Labour Market Statistical Bulletins and on the NOMIS ® website. Long run quarterly time series by industry, region, gender and full/part-time are available. The LFS and WFJ measures are reconciled each quarter. Job vacancies are measured separately by the Vacancy Survey.
WFJ estimates are subject to various sources of error that can be categorised into sampling error and non-sampling error.
Sampling error occurs for survey estimates that are based on samples rather than a census. Since March 2013, ONS has published approximate sampling variability information for workforce jobs which will be updated on an annual basis. Further information about the development of sampling variability estimates for workforce jobs is available in an article on the website (53.5 Kb Pdf) .
The estimated 95% confidence interval (the range around an estimate which in 95% of cases will include the true value) for quarterly Workforce Jobs estimates is between +/- 200,000 to 300,000 jobs, a coefficient of variation of approximately +/- 0.5%.
Non-sampling errors include errors of coverage, measurement, processing and non-response and are difficult to quantify. The employer surveys usually exceed a monthly response rate of 80 per cent. Reliability can be assessed by analysing the revisions between subsequent releases. Revisions are standard practice when producing official statistics and can occur if more information becomes available, if errors are corrected or methods changed.
The revisions policy for WFJ is to open at least the previous quarter for revision. All periods are usually open in the December release to coincide with the annual benchmarking exercise and seasonal adjustment review. Revisions articles are published to explain the revisions as set out in the National Statistics Code of practice. The various WFJ sources use different reference points. The reference point for short-tem employment surveys (STES) is linked to the claimant count date and is the Friday following the second Thursday of the last month in the quarter (March for quarter one, June for quarter two, September for quarter three and December for quarter four).
The Quarterly Public Sector Employment Survey (115.9 Kb Pdf) uses the last working day of the last month in the quarter. The self-employment jobs series from the LFS are three-month averages centred on the employment month, for example, February to April for the first quarter.
Quarterly WFJ estimates are published in the Labour Market Statistics Release approximately two-and-a-half months after the reference month.
The ONS Vacancy Survey (111.9 Kb Pdf) provides comprehensive estimates of the number of job vacancies across the UK economy. This monthly survey asks employers how many job vacancies they have in total for which they are actively seeking recruits from outside their organisation, for example, by advertising or interviewing.The survey began in April 2001 and the results became National Statistics in June 2003. The results are published in the Labour Market Statistical Bulletin. The headline series are seasonally adjusted three-month rolling averages. Analysis is available by industry and by size of enterprise. Analysis is available by industry and by size of enterprise, but no regional analysis is available.
Approximately 6,000 enterprises in Great Britain are surveyed on a specific date each month. Employers are asked to return just one number by telephone data entry using their keypad. In common with the majority of ONS business surveys, the sample is obtained from the Inter-Departmental Business Register (IDBR), stratified by industry and number of people employed.
One quarter of the sample consists of large businesses or organisations that are included every month. The remaining 4,500 are smaller and are sampled randomly on a quarterly basis. Smaller businesses remain in the survey for five or nine quarters (depending on the size of the business).
The survey covers all industrial sectors except agriculture, forestry and fishing. This is because of the disproportionate additional costs involved and the difficulties of measuring vacancies in these industry sectors, which mainly consist of very small firms (mostly with no vacancies). It is common practice to exclude these sectors from vacancy surveys in other countries. The UK approach is consistent with EU requirements.
Completion of the survey is compulsory under the Statistics of Trade Act 1947. The survey covers businesses in Great Britain only, although estimates for the UK are derived by grossing up the data for Great Britain, along with information about employment in Northern Ireland businesses. Businesses in Northern Ireland are not surveyed because of the risk of overlap with responses to other surveys conducted by Northern Ireland departments.

Details of the policy governing the release of new data are available by visiting www.statisticsauthority.gov.uk/assessment/code-of-practice/index.html or from the Media Relations Office email: firstname.lastname@example.org
Actual hours worked
Statistics for actual weekly hours worked measure how many hours were actually worked. These statistics are affected directly by changes in the number of people in employment and in the number of hours that individuals work. The figures are seasonally adjusted to take account of calendar-related absences from work during the reference period. Examples of such absences are public holidays and time off work for family or school holidays. The figures are also affected by other absences from work such as those due to sickness.
An allowance is an entitlement granted by the employer to an employee and intended to cover a specific expense, not work-related, incurred by the employee. It is often stipulated in workplace agreements and is normally paid at the time of entitlement.
Annual Population Survey (APS)
The Annual Population Survey is similar to the Labour Force Survey (LFS). It started in January 2004 and is compiled by taking data from the four calendar quarters of the LFS and combining them with additional samples of interviews.
Annual Survey of Hours and Earnings (ASHE)
The Annual Survey of Hours and Earnings is a survey conducted by the Office for National Statistics (ONS) that provides information about the levels, distribution and make-up of earnings and paid hours for employees in all industries and occupations.
Average Weekly Earnings (AWE)
Average Weekly Earnings is the lead monthly measure of average weekly earnings per employee. It is calculated using information based on the Monthly Wages and Salaries Survey (MWSS), which samples 8,500 firms in Great Britain. It is produced by the Office for National Statistics (ONS) and provides a key measure of wage inflation. It replaced the Average Earnings Index as the ONS’s headline measure of short-term earnings growth in January 2010.
Benefits in Kind
These are benefits, excluding salaries, given to employees which include cars and car fuel, medical insurance and gifts, and which are taxed as employment income.
A bonus is a form of reward or recognition granted by an employer. When an employee receives a bonus payment, there is no expectation or assumption that the bonus will be used to cover any specific expense. The value and timing of a bonus payment can be at the discretion of the employer or stipulated in workplace agreements.
Sometimes referred to as VICS (volume indices of capital services), these are measures of capital inputs which reflect the flow of productive capital into production (rather than the value of capital employed). Capital services are used in the construction of estimates of multi-factor productivity.
The number of people claiming unemployment-related benefits. Since October 1996 this has been the number of people claiming Jobseeker's Allowance. The seasonally adjusted claimant count series, which goes back to 1971 for the UK, is estimated on a basis consistent with the current benefits regime, that is, it has been adjusted for discontinuities in coverage.
Claimant Count rate
The number of claimants resident in an area as a percentage of the sum of claimants and workforce jobs in the country or region.
Compensation of employees
Defined as the total remuneration, in cash or in kind, payable by an employer to an employee in return for employers' social contributions, mainly consisting of employers' actual social contributions (excluding apprentices), employers' imputed social contributions (excluding apprentices) and employers' social contributions for apprentices.
A sub group of the economically inactive population who said their main reason for not seeking work was because they believed there were no jobs available.
Duration of Employment (Job Tenure)
Duration of employment, often referred to as job tenure, can be viewed in two ways. Firstly, it can refer to the length of time an individual spends in continuous employment, regardless of whether they are with the same employer. Alternatively, it can refer to the length of time the individual remains with the same employer, either in the same job or in different positions within the organisation. The Labour Force Survey (LFS) asks a number of questions in order to collect the time periods for which respondents have been with their current and/or previous employer.
A measure of the money people receive in return for work done, gross of tax. It includes salaries and, unless otherwise stated, bonuses but not unearned income, benefits in kind or arrears of pay.
People aged 16 and over who are either in employment or unemployed.
The number of people in employment is measured by the Labour Force Survey (LFS) and consists of people aged 16 and over who did paid work (as an employee or self-employed), those who had a job that they were temporarily away from, those placed with employers on government-supported training and employment programmes, and those doing unpaid family work.
Employment and jobs
The number of people with jobs is not the same as the number of jobs. This is because a person can have more than one job. The number of people with jobs is measured by the Labour Force Survey (LFS). The number of jobs is measured by Workforce Jobs (WFJ) and is the sum of employee jobs from employer surveys, self-employment jobs from the LFS, those in HM Forces and Government-Supported Trainees. The LFS also provides an estimate of the number of jobs, by adding main and second jobs, but the industry breakdown is less reliable. The LFS and WFJ measures are reconciled each quarter in an article published on the website. Jobs vacancies are measured separately by the Vacancy Survey.
The headline employment rate is calculated by dividing the employment level for those aged from 16 to 64 by the population for that age group.
The enterprise is the smallest combination of legal units that is an organisational unit producing goods or services, which benefits from a certain degree of autonomy in decision making, especially for the allocation of its current resources. An enterprise carries out one or more activities at one or more locations. An enterprise may be a sole legal unit.
Full-time and part-time
In the Labour Force Survey (LFS), respondents are asked to self-classify their main job as either full-time or part-time.
Gross Value Added (GVA)
The additional value generated by any unit engaged in production, over and above the value of the inputs to that production. It can also be defined as the difference between total output and intermediate consumption for any given sector or industry. It is measured at basic prices, excluding taxes less subsidies on products.
See Actual Hours Worked and Usual Hours Worked.
Economically inactive people are those without a job who have not actively sought work in the last four weeks, and/or are not available to start work in the next two weeks.
The headline inactivity rate is calculated by dividing the inactivity level for those aged from 16 to 64 divided by the population for that age group.
A measure of the average level of prices, quantities or other quantifiable characteristics relative to their level for a defined reference period or location. It is usually expressed as relative to 100 (for example, 105 would be an increase of 5 per cent) where 100 is the value for the reference period or location.
Index of Labour Costs per Hour (ILCH)
The Index of Labour Costs per Hour is an experimental quarterly measure to estimate the changes in the cost incurred for an hourly unit of labour provided by an employee to an employer. It is calculated using information based on the Monthly Wages and Salaries Survey (MWSS), which samples 8,500 firms in Great Britain. It is produced by the Office for National Statistics (ONS) and provides a key measure of inflation.
This is the internationally standardised method for classifying the extensive range of industrial sectors in an economy. At the highest level, the economy can be divided into the private sector and the public sector. It can also be broken down by industrial sector. ONS uses the Standard Industrial Classification 2007 (SIC 2007) for industrial breakdowns of labour market statistics.
Inflows and Outflows
The claimant count records are analysed to provide information about inflows into the count and outflows from the count on a monthly basis. To make comparisons over time consistent, these figures are standardised to a four and three quarter week month before seasonal adjustment. These figures for people starting to or ceasing to claim Jobseekers Allowance can be helpful towards intepreting changes in the claimant count.
Inter-Departmental Business Register (IDBR)
The UK register for business surveys. The register is used to select businesses to be included in the surveys, mail forms, enable estimates to be made for businesses that do not respond, or who were not asked to participate in any particular survey, and to produce analyses.
Jobcentre Plus is a government agency supporting people of working age from welfare into work, and helping employers to fill their vacancies. It is part of the Department for Work and Pensions (DWP) and it administers Jobseeker’s Allowance benefit and a number of other benefits.
Job related training
Job related training is a combination of work and preparing for work. It includes on the job training, training away from the job and pre-employment training.
A job is an activity performed for an employer or customer by a worker in exchange for payment, usually in cash, in kind, or both. Agreement is reached through the provision and negotiation of a contract, stipulating what an employer or customer demands and what is to be supplied by the worker. Estimates of jobs are published in the workforce jobs series which is mainly sourced from employer surveys.
Jobseeker's Allowance (JSA)
Jobseeker’s Allowance is the main benefit for people of working age who are out of work or work less than 16 hours a week on average. If you're eligible, it is paid while you're looking for work. To get Jobseeker's Allowance you must be (i) available for, capable and actively seeking work, (ii) aged 18 or over but below State Pension age, (iii) working less than 16 hours per week on average. Jobseeker's Allowance is not normally paid to 16 or 17 year olds, except in special cases.
See Duration of Employment.
Key out of work benefits
The Department for Work & Pensions consider the key out of work benefits to be those that are paid to client groups subject to labour market activation policies. This includes recipients of Jobseeker's Allowance, Incapacity Benefit, Employment & Support Allowance, Severe Disablement Allowance, Lone Parents Income Support and other income related benefits. However it excludes recipients of Carers Allowance, Bereavement or Widow's Benefit and Disability Living Allowance, unless the claimant is also in receipt of one of the key out of work benefits.
In the employed sector, this is largely made up of wages and salaries, but there are some other components that are added to wages and salaries to make up ‘Compensation of Employees’. These other components include other forms of remuneration such as national insurance or pension contributions. For the self-employed sector, it is not possible to attribute income specifically to labour or to capital, so the returns to labour and capital are grouped into one term called ‘Mixed Income’. However, for some productivity measures, notably unit wage costs, it is necessary to derive an estimate for the returns to self-employed labour. This is done by assuming that the proportions of either hours worked or returns to labour are the same in the self-employed sector as they are in the employed sector.
Disputes connected with terms and conditions of employment. These statistics relate to persons both directly and indirectly involved at the establishments where the disputes occurred.
Labour Force Survey
The Labour Force Survey (LFS) is the largest regular household survey in the UK. The survey covers people resident in private households, National Health Service (NHS) accommodation and student halls of residence. It does not cover any other communal establishments. LFS interviews are conducted continuously throughout the year. In any three-month period, a nationally representative sample of approximately 100,000 people aged 16 and over in around 45,000 households is interviewed. Each household is interviewed five times, at three monthly intervals. The initial interview is conducted face-to-face by an interviewer visiting the address, except for residences north of the Caledonian Canal in Scotland (where face-to-face-interviews would be prohibitively expensive). The other interviews are conducted by telephone wherever possible. The survey asks a series of questions about respondents’ personal circumstances and their labour market activity. The survey is conducted in five ‘waves’ so that in any one quarter, one wave will be receiving their first interview, one wave their second, and so on, with one wave receiving their fifth and final interview. Therefore, there is an 80 per cent overlap in the samples for each successive quarter.
In terms of input to productivity measures, this is the flow of productive labour.
Labour Market Statistics (LMS)
A measure of many different aspects of the labour market that provide an insight into the economy. They are also very much about people, including: their participation in the labour force; the types of work they do; earnings and benefits they receive; their educational qualifications; and their working patterns.
Local Unit (LU) employees
The industrial classification of the local unit of an enterprise is used to classify employee jobs, rather than the ‘reporting unit’ industrial classification. This is particularly relevant when an enterprise has numerous local units in more than one industrial function and in more than one geographical region. For example, a supermarket may provide pharmaceutical services, insurance and various other services besides selling supermarket-related goods and services, predominantly food and other domestic or household goods.
Monthly Wages and Salaries Survey (MWSS)
A survey conducted by the Office for National Statistics (ONS) which collects information on wages and salaries. The survey is distributed monthly to over 8,800 businesses covering some 12.8 million employees.
Multifactor productivity (MFP)
Also sometimes referred to as ‘total factor productivity’, ‘disembodied technical change’ or the ‘Solow residual’. This is an alternative, more complex, method of estimating productivity growth. ONS estimates of MFP can be thought of as that part of a recorded change in economic output that cannot be accounted for by changes in inputs of labour (measured by QALI) and capital services. For example, improved management techniques which lead to more output from given inputs of labour and capital will lead to an increase in MFP.

See full-time and part-time.
Quality adjusted labour input (QALI)
Measures of labour input which take account of changes in the composition of labour differentiated by educational qualification, industry of employment, age and gender. For example, a shift in the composition of the employed labour force towards higher levels of educational qualification will lead to QALI growing faster than the rate of growth of hours worked. QALI estimates are used in the construction of estimates of multi-factor productivity.
Generally, the preferred measure of Labour market statistics as they allow changes in the labour market to be interpreted in a wider context by allowing for changes in the overall population.
The number of people, whether working or not working, who had been made redundant or had taken voluntary redundancy in the month of the Labour Force Survey reference week or in the previous two calendar months.
Survey estimates are prone to sampling variability. The easiest way to explain this is by example. In the April to June 2008 period, there were estimated to be 29,558,000 people aged 16 and over in employment in the UK, according to the LFS (seasonally adjusted). These figures were published in August 2008. If we drew another sample for the same period we could get a different result, which could be higher or lower. In theory, we could draw many samples, and each would give a different result. The spread of these results leads to sampling variability. Once we know the sampling variability we can calculate a range of values about the sample estimate that represents the expected variation with a given level of assurance. This is called a confidence interval. For a 95 per cent confidence interval we expect that, in 95 per cent of the samples, the confidence interval will contain the true value of employment that would have been obtained by surveying the entire population. For example, for April to June 2008, we can be 95 per cent confident that the true level of employment was within 140,000 of the estimate of 29,558,000 (that is, within the range 29,418,000 to 29,698,000). Sampling variability also affects changes over time. Changes in employment between three-month periods are rarely greater than the level that is explainable by sampling variability. It is estimated that the number of people aged 16 and over in employment in the UK increased by 20,000 between January to March 2008 and April to June 2008 (seasonally adjusted). We can be 95 per cent confident that the true change lies in the range between a decrease of 81,000 and an increase of 121,000. It is more likely that employment increased, rather than decreased. In general, the larger the number of people in the sample, the smaller the variation between estimates. Estimates based on the LFS for the whole of the UK are therefore more accurate than those for smaller geographical areas. Indications of sampling variability for national and regional LFS data are given in the Labour Market Release.
Seasonal movements can occur in labour market data for a number of reasons including holidays and recruitment patterns. For example, a large number of people leave full-time education and enter the labour market in the summer. To make it easier to identify the underlying movements in the labour market, changes due solely to seasonal influences are removed from many series. This process is known as seasonal adjustment. LFS estimates are seasonally adjusted using the X-12 ARIMA package developed by Statistics Canada. The seasonal adjustment of LFS data is usually reviewed annually.
The statistics cover stoppages of work in progress in the UK during a year caused by labour disputes between employers and workers, or between workers and other workers, connected with the terms and conditions of employment. These include ‘lock-outs’ by employers and ‘unlawful’ or ‘unofficial’ strikes. The statistics exclude disputes that do not result in a stoppage of work, for example, work-to-rules and go-slows.
The number of unemployed people in the UK is measured through the Labour Force Survey (LFS) following the internationally agreed definition recommended by the International Labour Organisation (ILO) – an agency of the United Nations. Unemployed people are without a job, have actively sought work in the last four weeks and are available to start work in the next two weeks or out of work, have found a job and are waiting to start it in the next two weeks.
The headline unemployment rate is calculated by dividing the unemployment level for those aged 16 and over by the total number of economically active people aged 16 and over. Economically active is defined as those in employment plus those who are unemployed.
Usual hours worked
Statistics for usual hours worked measure how many hours people usually work per week. Compared with actual hours worked, they are not affected by absences and so can provide a better measure of normal working patterns.
Vacancies are defined as positions for which employers are actively seeking recruits from outside their business or organisation. The estimates are based on the Vacancy Survey, a survey of businesses designed to provide estimates of the stock of vacancies across the economy, excluding Agriculture, forestry and fishing (a small sector for which the collection of estimates would not be practical).
The figures for workers involved in labour disputes are for workers both directly and indirectly involved at the establishment where the dispute occurred. Workers indirectly involved are those who are not themselves parties to the dispute but are laid off because of the dispute. Workers involved in more than one stoppage during the year are counted in the statistics for each stoppage in which they take part. Part-time workers are counted as whole units.
See Employment and Jobs.
Working Days Lost
Working days lost are defined as the number of days not worked by people involved in a dispute at their place of work. In measuring the number of working days lost, account is taken only of the time lost in the basic working week. Overtime work is excluded, as is weekend working where it is not regular practice.
