4. Quality summary

Overview

Business demography is an annual publication produced from the Inter-Departmental Business Register (IDBR). The publication focuses on changes to the registered business population, that is, those businesses registered at Her Majesty's Revenue and Customs (HMRC) for Value Added Tax (VAT) and/or Pay As You Earn (PAYE) and at Companies House.

Unlike the UK business: activity, size and location publication, which is a snapshot of a point in time on the IDBR, Business demography measures businesses that were active throughout the reference year. The reference period is December and therefore the 2017 publication measures businesses that were active between December 2016 and December 2017. Being active means that the business had either turnover or employment at any time during the reference year. The file of active businesses is compared with previous and subsequent files in order to identify business births and deaths and up to five-year survival rates.

The data have been produced in response to a European Union regulation and there are comparable data across European Union members. These data are a useful indicator of entrepreneurship and economic growth. The data tables in the publication are broken down by UK Standard Industrial Classification 2007: SIC 2007 and by geography down to local authority and district level.

Uses and users

The data in the publication are used extensively by central and local government, MPs and private sector users for a range of investigative, monitoring and planning purposes. The data are also used by academia and regularly by the media who consider this information to be an indicator on economic activities. The product is generally used by those who wish to examine the numbers of business births, deaths and survival in certain industries and/or geographical areas.

Specific uses of this product and the views of users can be seen in the UK Statistics Authority assessment report number 187: Statistics on UK business population and demography.

Strengths and limitations

The main administrative sources for the Inter-Departmental Business Register (IDBR) are VAT trader and PAYE employer information passed to Office for National Statistics (ONS) by HMRC under the Value Added Tax Act 1994 for VAT traders and the Finance Act 1969 for PAYE employers; details of incorporated businesses are also passed to ONS by Companies House. ONS survey data and survey information from the Northern Ireland Statistics and Research Agency (NISRA) and the Department for Environment, Food and Rural Affairs (Defra) farms register provide auxiliary information.

These comprehensive administrative sources combined with the survey data contribute to the coverage on the IDBR, which is one of its main strengths.

The IDBR provides a comprehensive coverage of businesses registered for VAT and/or PAYE, however, there exists a sizeable population of low turnover non-employing businesses that the IDBR does not include. These businesses are not included in the publication. It is currently estimated that in the UK there are 2.7 million registered businesses and 3.1 million unregistered businesses. The unregistered businesses are very small in terms of turnover and the vast majority of UK economic activity is captured through the 2.7 million registered businesses that are on the IDBR.

The Department for Business, Energy and Industrial Strategy (BEIS) produce a publication called Business population estimates and this provides an estimate of the total UK business population. (It includes an estimate of the “unregistered” population.) Further information on the three National Statistics publications that provide information on the UK business population can be found in the Coherence and comparability section.

To support the release a set of datasets in greater geographical and industrial detail have been produced. We recommend treating the data with caution when it is broken down to a lower geographical level. In recent years multiple registrations at a single postcode have caused large fluctuations in the data. A methodology article Multiple registrations at a single postcode has been produced regarding this issue.

Recent improvements

The Business demography publication reference period records the number of active businesses over a period of a year. Up to 2016, this was measured from a single point in November one year to a single point in November the following year. For example, the 2015 publication measured the number of active businesses taken from a specific date in November 2014 to the same date in November 2015. From 2016 onwards, the reference period moved to December. This has helped bring the reference period closer to the calendar year, as recommended by the joint Eurostat and Organisation for Economic Co-operation and Development (OECD) manual on business demography.

5. Quality characteristics of the Business demography data

This section provides a range of information that describes the quality and characteristics of the data and identifies issues that should be noted when using the output.

Accuracy and reliability

The publication is an extract from the Inter-Departmental Business Register (IDBR), which is based on administrative records, there is no estimation or imputation. However, it is important to note that underlying the extracts are IDBR processing rules, which impact, for example, on the timeliness and classification of businesses.

A more detailed article on the IDBR sources, structures and updating (PDF, 59KB) process is available.

Coherence and comparability

There are three National Statistics publications that provide information on the UK business population:

In addition to these publications, similar related National Statistics are released by the three devolved administrations for their countries, the Insolvency Service publishes National Statistics for corporate and individual insolvency and Companies House publishes statistics based on activity on their register. Table 1 describes the important features of the three UK business population publications.

Accessibility and clarity

Our recommended format for accessible content is a combination of HTML webpages for narrative, charts and graphs, with data being provided in usable formats such as CSV and Excel. Our website also offers users the option to download the narrative in PDF format. In some instances, other software may be used, or may be available on request. Available formats for content published on our website but not produced by us, or referenced on our website but stored elsewhere, may vary. For further information please refer to the contact details at the beginning of this report.

The Business demography publication started in 2009. The publications are available :

Please note that the 2009 publication contains data back to 2004.

In addition, we publish data requested on our website. If the information you need has not previously been published, please contact us with details of your requirements. Bespoke requests may be chargeable. If you would like further details, please contact idbrdas@ons.gov.uk.

Timeliness and punctuality

The Business demography reference period is December and the publication is released the following November. This translates into a time lag of approximately 11 months.

For more details on related releases, the GOV.UK release calendar provides 12 months’ advanced notice of release dates. If there are any changes to the pre-announced release schedule, public attention will be drawn to the change and the reasons for the change will be explained fully at the same time, as set out in the Code of Practice for Statistics.  

Concepts and definitions

The Business demography data have been produced in line with a European Union regulation – the Structural Business Statistics (SBS) recast Regulation 295/2008 – this specifies the need for the annual collection of these data. The methodology and definitions used in order to create the data can be found in the joint Eurostat and Organisation for Economic Co-operation and Development (OECD) manual on business demography.

Geography

Regional analyses are provided for Value Added Tax and/or Pay As You Earn - based businesses. The location of the business is generally the main operating site or the head office.

The geographies presented in the publication for England and Wales are created from Middle layer Super Output Areas (MSOA) derived from Output Area , the stable geographic building block now being used to produce statistics. District, county and region figures are aggregations of these MSOAs.

For Scotland, the geographies relate to “intermediate zones”, a layer equivalent to MSOA. From 2011, the Northern Ireland geographies relate to Lower layer Super Output Areas , a geographic hierarchy designed to improve the reporting of small area statistics.

Output quality

To publish estimates within a year of the reference period, we make an adjustment to the deaths figures to allow for reactivations.

The Eurostat and Organisation for Economic Co-operation and Development (OECD) manual on business demography recommends waiting for two years after the reference period to allow for reactivations before deaths figures are calculated. In the release, we estimate the number of reactivations and adjust the data accordingly.

The adjustment has been applied to all industries, by removing units from the death data. This can lead to different percentage adjustments at the lowest level of aggregation. In order to account for reactivations the death data are not final until the third year. The preceding two years of deaths are considered to be provisional and subject to revision. Table 8 of the datasets shows the adjustments made to the death data for reactivations.

Why you can trust our data

The Business demography publication is a National Statistic. It has been assessed and is fully compliant with the Code of Practice for Statistics (that is, it meets the highest standards of trustworthiness, quality and value as laid out in the Code).

6. Methods used to produce the Business demography data

How we collect the data, main data sources and accuracy

The information used to create and maintain the Inter-Departmental Business Register (IDBR) is obtained from five main administrative sources. These are:

  • HM Revenue and Customs (HMRC) Value Added Tax (VAT) – traders registered for VAT purposes with HMRC

  • HMRC Pay As You Earn (PAYE) – employers operating a PAYE scheme, registered with HMRC

  • Companies House – incorporated businesses registered at Companies House

  • Department for Environment, Food and Rural Affairs (Defra) farms

  • Department of Finance and Personnel, Northern Ireland (DFPNI)

As well as these five main sources, a commercial data provider, Dun and Bradstreet is used to supplement the IDBR with Enterprise Group information.

In addition, the Office for National Statistics (ONS) Business Register and Employment Survey (BRES) and other ONS surveys supplement these administrative sources, identifying and maintaining the business structures necessary to produce detailed industry and small area statistics. It should be noted that BRES is the only source of local unit (site) information. It is used to populate the employment and classification of a business.

A more detailed article on the IDBR sources, structures and updating (PDF, 59KB) process is available.

How we process and quality assure the data

Since the publication is an extract from the Inter-Departmental Business Register (IDBR), which is based on administrative records, there is no estimation or imputation. However, it is important to note that underlying the extracts are IDBR processing rules, which impact, for example, on the timeliness and classification of businesses.

Information on the administrative source data used to construct and compile the IDBR, the quality control checks, processes and maintenance procedures are described in the article Introduction to the Inter-Departmental Business Register.

The constituent data used to populate the IDBR are received from the administrative sources daily and are subjected to rigorous testing and quality control checks before being uploaded onto the IDBR. Checks include matching HMRC VAT and PAYE information, checking that business locations and structures match PAYE and VAT information, employment data are correct, businesses are active and allocating businesses to correct standard industrial classifications. These tasks are carried out via automatic system checks, with any changes or errors reported for manual investigation, checking before correction and subsequent uploading.

IDBR data are extracted for the publication and placed into a series of pre-defined tables using SAS Enterprise Guide software. Data in each of the tables are then quality checked to ensure that information has been extracted correctly and reflects the information contained on the IDBR.

Statistical disclosure control methodology is also applied to the data to ensure that information attributable to an individual organisation is not disclosed.

How we analyse and interpret the data

The starting point for the calculation of Business demography data is the concept of active businesses in a reference year. These are defined as businesses that had either turnover or employment at any time during the reference period. New business registrations are referred to as business births and the birth rate is calculated using the number of births as a proportion of the active businesses.

Businesses that have ceased to trade (identified through de-registration of the administrative units, that is, VAT and PAYE) are referred to as business deaths. The death rate is calculated using the number of deaths as a proportion of the active businesses.

Once the data tables have been created continuity checks and investigations into data value changes are carried out. Comparisons are made against previous years’ data values to ensure that data movements, for example, large changes in counts for geographies or industries, are correct. If appropriate and significant, these fluctuations are reported in the statistical bulletin.

How we disseminate the data

Business demography is released via the ONS website as an Excel dataset accompanied by a statistical bulletin explaining headline figures and changes. Publication dates are available via the GOV.UK release calendar.

How we review and maintain the data processes

The Business demography datasets present analysis of VAT and/or PAYE-registered businesses by their business activity and their geographical location.

The views and requirements of government and non-government users of this product are sought regularly. The following methods are utilised for engaging with users:

  • an ONS and BEIS jointly-convened Business Population and Demographic Statistics (BPDS) User Group; this group, which meets once a year, has been created to specifically engage with both government and non-government users at the same time with the intention of seeking their views and opinions about BPDS outputs and future developments

  • Government Statistical Service Business Registers Group; this is a cross-governmental group that identifies and addresses developments and issues affecting the IDBR; this group meets biannually
