Output per hour in the UK was 17 percentage points below the average for the rest of the major G7 industrialised economies in 2013, the widest productivity gap since 1992. On an output per worker basis, UK productivity was 19 percentage points below the average for the rest of the G7 in 2013
UK output per hour fell slightly in 2013 compared with 2012, contrasting with an increase of 1.0% across the rest of the G7
In 2013 UK output per hour was roughly unchanged from its level in the pre-downturn year of 2007, but some 15-16 percentage points below a counterfactual level had the UK's strong productivity growth prior to the downturn continued. The productivity gap on the same basis for the rest of the G7 is around 6 percentage points
As well as first estimates for 2013, this release includes revised GDP estimates for the UK, Germany, France and Italy resulting from adoption of new National Accounts reporting standards and other methodological changes
This bulletin contains annual estimates of labour productivity for the G7 developed countries (Canada, France, Germany, Italy, Japan, UK and USA) up to 2013. Labour productivity measures the amount of economic output that is produced by a unit of labour input, and is a key indicator of economic performance.
Output is measured by gross domestic product (GDP). Labour input is measured in two ways – by total hours worked and by numbers of workers in employment. These two measures of labour input can yield different results, reflecting differences in working patterns across countries and compositional movements over time, such as a shift towards part-time working.
Comparability across countries is achieved by converting local currency based measures of GDP using purchasing power parity (PPP) exchange rates. PPP exchange rates (usually referred to simply as PPPs) attempt to equalise the cost of a representative basket of goods and services in countries with different national currencies. An ONS article explaining the uses and limitations of PPPs (246.1 Kb Pdf) is available on our website.
The estimates in this release update those published on 20 February 2014. This release cycle reflects the publication and revision cycles of the component data series.Back to table of contents
This release includes first estimates for 2013. In addition, GDP estimates for the UK, Germany, France and Italy reflect the adoption of a new National Accounting standard known as ESA 2010. These revisions bring these countries GDP estimates broadly into line, methodologically, with those for the US and Canada, but the new accounting standard has not yet been adopted in Japan.
Estimates of constant price productivity in Tables 3 and 4 are now rounded to one decimal place, and revisions to previously published constant price estimates are now presented in terms of differences in annual growth rates.Back to table of contents
The labour productivity measures in this bulletin are presented in terms of current prices, suitable for cross-country comparison of levels of productivity for a single year, and constant prices, suitable for analysis of productivity performance over a number of years. The current price estimates in Tables 1 and 2 should be read horizontally, while the constant price estimates in Tables 3 and 4 should be read vertically.
Current price productivity estimates are indexed spatially to UK=100 for each year and show each country’s productivity relative to that of the UK in that year. Since productivity is a key determinant of living standards, these estimates also provide an indication of living standards relative to the UK.
In interpreting these estimates users should bear in mind that PPPs provide only an approximate conversion from national currencies and may not fully reflect national differences in the composition of a representative basket of goods and services. Additionally, care should be taken in interpreting movements in current price productivity estimates over time. For example, an increase in UK productivity relative to another country from one year to another could be due to UK productivity growing faster, or falling less, or due to changes in relative prices in the two countries, or some combination of these movements.
Constant price productivity estimates are indexed to a particular year. For each single country, these estimates are conceptually similar to national labour productivity series (minor differences from national sources are described in the Background Notes to this bulletin). The index year is set at 2007 in order to focus on movements in labour productivity over the economic downturn.
Constant price productivity estimates show the evolution of productivity for each country and for the G7 (and G7 excluding the UK) aggregates, but should not be used to compare productivity across countries at a point in time. Productivity growth can be decomposed into growth of output minus the growth of labour input, and these components can move in different directions within and across countries. This should be borne in mind in interpreting the constant price productivity estimates in this release.
More information on methodology and interpretation is available in the Background Notes to this bulletin. Additionally, the Quality and Methodology Information paper (123.8 Kb Pdf) for this release provides information on the quality of the estimates in this release, as well as providing a summary of methods used in compiling the estimates.Back to table of contents
Current price productivity estimates allow for comparison of how much economic output, measured in common currency terms, is produced by each worker and hour worked across countries in a particular year, relative to the UK=100. Further information is available in Tables 1 and 2 in the reference table (128.5 Kb Excel sheet) component of this release and at the back of the PDF version of this statistical bulletin.
GDP per hour worked (Table 1)
On this basis, UK productivity in 2013 was:
Above that of Japan by 15 percentage points
Roughly equal to that of Canada
Lower than that of Italy by 9 percentage points
Lower than that of the remaining G7 countries by 28 to 30 percentage points
Figure 1: GDP per hour worked, G7 countries

Comparing 2013 with 2012, these first estimates show very little change in relative UK productivity levels. The difference in productivity on this measure between the UK and the rest of the G7 was 17 percentage points in 2013, unchanged from 2012 and the widest differential since 1992.
GDP per worker (Table 2)
First estimates for 2013 show that UK output per worker was:
Above that of Japan by 12 percentage points
Below that of Canada and Germany by 3 and 7 percentage points respectively
Below that of Italy and France by 14 to 15 percentage points
Below that of the US by 39 percentage points
Figure 2: GDP per worker, G7 countries

Comparing 2013 with 2012, the shortfall between output per worker in the UK and the rest of the G7 decreased by 1 percentage point, and there were relative improvements against each of the constituent countries.
As illustrated in Figure 3, there are significant differences in average hours worked across the G7, reflecting cultural and compositional differences between economies. The general trend across the G7 as a whole is towards lower hours. Different movements in average hours across countries account for differences in the patterns of productivity in Figures 1 and 2; in particular, there has been a distinct upturn in average hours worked in the UK in each of 2012 and 2013. The difference in average hours worked in 2013 between the US (where average hours are highest across the G7) and Germany (lowest) is equivalent to around 8 hours per week for the average worker. Average hours worked in the UK are close to the average for the G7 as a whole.

Constant price productivity estimates are indexed to 2007=100 and show the evolution of labour productivity for each country and group of countries over time. Further information is available in Table 3 (GDP per hour worked) and Table 4 (GDP per worker) in the reference table (128.5 Kb Excel sheet) component of this release and at the back of the PDF version of this statistical bulletin. The following commentary focuses on GDP per hour worked, which is a more comprehensive measure of productivity than GDP per worker.
Figure 4 shows GDP per hour worked for the UK and an aggregated series for the rest of the G7, together with simple projections based on average productivity growth over 1997-2007, that is, before the global economic downturn. On this basis, the combination of strong UK productivity growth up to 2007 and weak productivity performance since 2007 implies a productivity gap of some 15-16% in 2013. Revisions to UK GDP have increased its level significantly, but revisions to GDP growth rates have been much more modest, such that the productivity gap on the latest estimates is only marginally narrower than on the previous estimates.
Average annual productivity growth between 1997 and 2007 for the rest of the G7 was lower than in the UK (around 1.8%, compared with 2.3% for the UK), and productivity performance since 2007 has on average been somewhat stronger, implying a productivity gap of around 6% in 2013.
Figure 5 illustrates the difference in productivity trajectories over recent years between the main European economies on the one hand, and North America and Japan on the other hand. Output per hour fell sharply in most countries over the 2008-09 downturn, but then rebounded sharply in Japan, Canada and especially the US, whereas the recovery in productivity has been more muted in France, and much weaker, in line with the UK experience, in Germany and Italy.
However, converting the time series in Figure 5 into productivity gaps (calculated as in Figure 4) for 2013 would yield gaps of 11% for Germany but only 4% for Italy. This is because Italy's trend productivity growth in the period prior to the economic downturn (about 0.5% per year) was much weaker than Germany's trend productivity growth of 1.7% per year.Back to table of contents
The main revisions in this release are to GDP, including but not limited to changes reflecting new international reporting standards:
Canada (in 2010) and the USA (in 2013) have already implemented changes under the System of National Accounts 2008 (SNA08)
The four European members of the G7 (UK, Germany, France and Italy) implemented changes under the European System of Accounts 2010 (ESA10, which is broadly comparable with SNA08) in 2014, incorporated for the first time in this release
Japan has not yet implemented SNA08 and will not do so until 2016
One important feature of SNA08 and ESA10 is the re-classification of R&D expenditure as asset accumulation rather than current expenditure. This increases measured GDP
In some cases, changes to the National Accounts go beyond those required under SNA08/ESA10. For example, the UK has introduced improvements to the estimation of gross fixed capital formation (separate from the capitalisation of R&D)
Interpretation of SNA08/ESA10 can differ between countries
More information is available on the OECD website. Taking all National Accounts revisions together, France and Germany have revised the level of GDP (in both current prices and volume terms) upwards by about 3% on average over the period since 1990, while in Italy the upward revisions average 3.6%. UK current price GDP has been revised upwards by 4.4% on average over this period, and the volume estimate has been revised upwards by 5.4%1. Generally, revisions to GDP growth rates are much smaller than revisions to GDP levels. For Germany and Italy there are no significant changes to (constant price) GDP growth over the period since 1990. French average GDP growth has been revised up by 0.1% per year and UK average GDP growth has been revised down by 0.1% per year over this period.
Other revisions include:
USA current and constant price GDP has been revised down in 2011 and 2012, reflecting the annual revision of the National Income and Product Accounts. A detailed explanation of these revisions is available on the Bureau of Economic Analysis website
PPP exchange rates have been revised in 2012. The effect of these revisions is to reduce the value of GDP in US dollar terms for all countries other than the USA (thus tending to increase US productivity relative top other countries)
French average hours worked have been revised up by about 1% on average over the entire time series
There are no material changes to employment in any of the G72
Tables R1 to R4 in the reference table (128.5 Kb Excel sheet) component of this release and at the back of the PDF version of this statistical bulletin compare the latest estimates data with the data from the previous release on 20 February 2014. Note that because Tables 1 and 2 are indexed to UK=100, revisions to the UK are zero by definition in Tables R1 and R2. Nevertheless, the largest factor in the revisions to other countries estimates (that is, in their relative productivity in relation to that of the UK) is the revisions to UK GDP series. For example, there are no revisions to the components of current price output per head and per worker in Canada or Japan prior to 2012, so all of the revisions for these countries in Tables R1 and R2 over the period 1990 to 2011 reflect UK revisions.
Revisions to constant price productivity in Tables R3 and R4 are now presented in terms of differences in growth rates. Revisions are dominated by changes in constant price GDP. On average over the whole period, growth of output per hour has been revised up by 0.1% per year in France and down by 0.1% per year in the UK. Growth of output per hour has been revised down by 0.5 percentage points in the US in 2012.
Notes for Revisions
At the time of preparing this release, OECD GDP data for the UK prior to 1997 reflected UK data as published on the ONS website on 31 September 2014. For these years, this release uses revised UK GDP data as published on the ONS website on 6 October 2014
Headline revisions to UK employment arising from revised population weights reflecting the 2011 Census were published by ONS on 23 September 2014. The re-weighted series are not incorporated in the employment series used in this release. The impact of the revisions is to increase aggregate employment since 2001 which, other things equal, implies lower levels of productivity. Revisions to employment growth rates are very small and will not materially change the path of productivity growth
