1. Main points

  • The levels of labour productivity (output per hour worked) for London and the South East were substantially above the median region in 2019, while most regions were much closer to the median; output per job follows a similar pattern.

  • Productivity grew in half of the 12 International Territorial Level (ITL1) regions of the UK in 2019, with Wales growing fastest, by more than 2%; in contrast, Northern Ireland productivity fell the most, by nearly 3%.

  • In 2019, London positively contributed 0.3 percentage points to overall growth in UK output per hour, more than any other region; whereas the South East negatively contributed to overall UK productivity by 0.3 percentage points.

2. Productivity levels across regions

Labour productivity is calculated by dividing output (gross value added, GVA) by a measure of labour input (total hours worked or jobs). National productivity statistics published in our regular productivity bulletins do not provide information about the productivity levels of the different geographical regions of the UK. We do this by splitting the UK into the 12 International Territorial Level (ITL1) regions. Later this year an accompanying article will examine productivity at lower geographical levels.

This analysis uses national price deflators, so it may fail to take account of differences in the level of prices in the different regions and countries of the UK.

Our main measure of productivity is output per hour worked, and this article is based on output for 2019, the most recent annual estimates of economic activity by UK country, region and local area.

Figure 1 shows relative levels of output per hour for each UK region in 2019. London had the highest productivity of any UK region, with output per hour nearly 50% higher than the median region. Output per hour levels for the South East, Scotland and the East of England were also above the median. Northern Ireland had the lowest level of output per hour in the UK, and other regions clustered close to the median level.

Output per job is an alternative measure of labour productivity and can produce different results if average hour worked per job vary across regions. Figure 2 shows the levels of output per job observed in each region compared with the median across regions. Similar to output per hour worked in Figure 1, London has levels of output per job well above the UK average. The other regions follow a similar pattern in this measure as they do in output per hour worked.

When regions are ranked by output per job instead of output per hour, Northern Ireland rose three places, suggesting that on average, workers in Northern Ireland worked longer hours for each job compared with the UK average (see section 4).

3. Productivity growth across regions

Productivity growth is important because increases in output per hour worked allow salaries and profits to rise, standards of living to improve, and allow society to fund better public services. In the long-run, regions that experience faster, sustained growth in productivity should have greater levels of prosperity than other regions. Figure 3 shows the growth of output per hour in each International Territorial Level (ITL1) region in 2019.

Half of the UK's 12 ITL1 regions experienced growth in output per hour in 2019, while the other half contracted. The highest growth of output per hour was 2.5% in Wales, whereas the largest fall was by 2.8% in Northern Ireland. Although productivity growth is increasing in certain areas of the North of England and Midlands, their productivity levels remain lower than the South of England.

Shifts of economic activity from one region to another (the allocation effect) can be an important factor for productivity growth. Figure 4 shows the contribution of each region to the total output per hour growth alongside the allocation effect, of which there was zero. In 2019, London contributed the most to UK output per hour growth. Despite having the fastest output per hour growth rate, Wales made only the third-largest contribution to growth, as the total number of hours worked is relatively low in Wales compared with other regions. In contrast, the South East showed the greatest negative contribution to growth despite only having the third-largest productivity decline; this is because of its large share of total hours worked in the economy.

6. Glossary

Labour inputs

Labour inputs in this release are measured in terms of jobs ("productivity jobs") and hours worked ("productivity hours"), for an industry within a geographic area.

Labour productivity

Labour productivity is calculated by dividing output by labour input.

Output

Output refers to gross value added (GVA), which is an estimate of the volume of goods and services produced after subtracting the volume of intermediate goods and services used in the production process (intermediate consumption). It is measured by industry within a geographic area, and in aggregate across industries for a geographic area.

Region

One of the 12 regions or devolved nations of the UK distinguished by International Territorial Level (ITL1) regions.

7. Measuring the data

Data in this release, and in the productivity estimates published alongside, are consistent with Blue Book 2020 data. They therefore do not reflect revisions outlined in our recent article on the impact of Blue Book 2021 changes (including double deflation) on labour productivity. Those changes will be implemented in quarterly productivity estimates from October 2021, after the quarterly national accounts in September 2021.

Two measures of output are used in these statistics, both from regional gross value added (balanced) by industry: all ITL1 level regions, a new classification system introduced in January 2021. For comparing levels of output per hour across industries or regions, output is the current price estimate of economic activity using nominal output (current prices) and may be subject to unmeasured differences in regional prices. For assessing rates of growth in output per hour from one year to another, output is the chained volume measure of gross value added (GVA).

Labour input measures used in this bulletin are known as "productivity jobs" and "productivity hours".

For estimates of regional productivity relative to the UK, productivity jobs is calculated by summing numbers of employees, the self-employed and two smaller components: Her Majesty's Forces (HMF) and government-supported trainees (GST). These data come from two principal sources within the Office for National Statistics (ONS): Short-Term Employment Survey (STES) data and the Labour Force Survey (LFS). Productivity hours are derived from estimates of average hours (derived from the LFS micro-dataset) and productivity jobs.

Information on the industry by region estimates of labour can be found in Introducing industry-by-region labour metrics and productivity: 2015.

Quality

More quality and methodology information on strengths, limitations, appropriate uses, and how the data were created is available in the Labour productivity QMI and Introducing industry-by-region labour metrics and productivity: 2015.

8. Strengths and limitations

This release reports labour productivity estimates for 2019 for International Territorial Level (ITL1) regions and for section-level industries within regions. Productivity is important because it is the long-term driver of changes in average living standards.

Figures in this release reflect data in the dataset labelled PRODBYREG. The dataset contains National Statistics on output per hour worked and output per job for each of the 12 ITL1 regions.

Data by industry and region are available in the accompanying dataset labelled INDBYREG, which are Experimental Statistics.

Comparability and consistency

The output statistics in this release are consistent with the latest analysis on Regional economic activity by gross domestic product, UK published on 26 May 2021. Productivity in this release uses measures of labour derived from the working population, unlike measures of regional gross value added (GVA) per head.

The labour input measures used in this release are calculated from the latest Short-Term Employment Survey (STES) data and the Labour Force Survey (LFS) from the Office for National Statistics. Other labour market statistics are available here.
