Labour Productivity, Q1 (Jan to Mar) 2015

  • UK labour productivity as measured by output per hour grew by 0.3% in the first quarter of 2015 compared with the previous quarter. This measure is 1.3% higher than the same period in 2014, the fastest annual growth since Q1 2012.
  • Whole economy unit labour costs decreased by 0.6% on the quarter and were 0.9% higher than a year ago. Growth of labour costs per hour remains subdued.
  • Output per hour in the manufacturing and production sectors fell on the quarter and on the year.
  • Output per hour grew in the services sector, though estimates of individual service industries were more mixed.
  • New for this release is an Industry Spotlight section, focusing on productivity in Information and communication services. This shows a pronounced slowdown in productivity in telecommunications services in recent years, after very strong growth prior to the economic downturn.

About this release

This release reports labour productivity estimates for the first quarter (Jan to Mar) of 2015 for the whole economy and a range of sub-industries, together with selected estimates of unit labour costs. Labour productivity measures the amount of real (inflation-adjusted) economic output that is produced by a unit of labour input (measured in this release in terms of workers, jobs and hours worked) and is an important indicator of economic performance.

Labour costs make up around two-thirds of the overall cost of production of UK economic output. Unit labour costs are therefore a closely watched indicator of inflationary pressures in the economy.

Output statistics in this release are consistent with the latest Quarterly National Accounts published on 30 June 2015. Labour input measures are consistent with the latest Labour Market Statistics as described further in the 'General commentary' and 'Notes on sources' sections below.

New for this release is an Industry Spotlight section, focusing on productivity in Information and communication services. New seasonal adjustment factors have altered the quarterly path of hours worked and improved the short-term tracking of output per hour. Further information is provided in the Revisions section below.

Interpreting these statistics

Whole economy output (measured by gross value added - GVA) increased by 0.4% in the first quarter of 2015, while the Labour Force Survey (LFS) shows that the number of workers, jobs and hours increased by 0.7%, 0.6% and 0.1% respectively over this period1. This combination of movements in outputs and labour inputs implies that labour productivity across the whole economy fell a little in terms of output per worker and output per job but increased a little in terms of output per hour.

Differences between growth of output per worker and output per job reflect changes in the ratio of jobs to workers. This ratio fell very slightly in Q1. Differences between these measures and output per hour reflect movements in average hours per job and per worker which, though typically not large from quarter to quarter, can be material over a period of time. For example, a shift towards part-time employment will tend to reduce average hours. For this reason, output per hour is a more comprehensive indicator of labour productivity and is the main focus of the commentary in this release.

Labour Productivity equation

Labour Productivity equation

This equation explains how Labour Productivity is calculated and how it can be derived using growth rates for GVA and labour inputs.

Unit labour costs (ULCs) reflect the full labour costs, including social security and employers’ pension contributions, incurred in the production of a unit of economic output, while unit wage costs (UWCs) are a narrower measure, excluding non-wage labour costs. Growth of ULCs can be decomposed as:

ULC equation

ULC equation

This equation explains how ULCs are calculated and how it can be derived from growth of labour costs per unit of labour (such as labour costs per hour worked) and growth of labour productivity.

In the first quarter, whole economy output per hour grew by 0.3% and ULCs fell by 0.6%. Plugging these values into the ULC equation and re-arranging yields an implied fall of approximately 0.3% in labour costs per hour. This implied movement differs from other ONS information on labour remuneration such as Average Weekly Earnings (AWE) and Indices of Labour Costs per Hour (ILCH), chiefly because the labour cost component includes estimated remuneration of self-employed labour, which is not included in AWE and ILCH.

Most of the series in this release are designated as National Statistics, meaning their production has been subject to rigorous quality assurance and methodological scrutiny. However, some service industry estimates use component series from the Index of Services (IOS) which are designated as experimental statistics (that is, not yet accredited as National Statistics, for example because the methodology is under development or reflecting concerns over data sources). Labour productivity estimates that use these series as their numerators are also labelled as experimental statistics. Market sector productivity estimates are also experimental series. More information on the experimental IOS series is available on the Guidance and methodology section of the ONS website.

Notes for Interpreting these statistics

  1. Growth rates for whole economy workers, jobs and hours shown in Table 10 of this release may differ slightly from growth rates based on LFS aggregate estimates due to different methods of seasonal adjustment.

General commentary

Productivity estimates are derived from estimates of labour inputs and economic outputs which are measured largely independently of one another. The buoyancy of the labour market has surprised many commentators and showed little sign of slowing in the first quarter. The number of recorded jobs grew by 2.4% in 2014, the fastest rate since 1989 and equivalent to average increases of 184 thousand jobs per quarter, while an additional 183 thousand jobs were added in the first quarter of 20151. Within these broad totals, full-time jobs have been increasing faster than part-time jobs, and employee jobs have increased faster than self-employment. Indeed, LFS estimates show that self-employment fell by 1.5% in the year to the first quarter.

The resilience of jobs in manufacturing is noteworthy. Over the 30 years prior to the economic downturn in 2008-09, the number of manufacturing jobs fell by around 3% per year on average, as the economy re-orientated itself towards the service sector and large swathes of manufacturing production moved overseas. Over the 4 years 2011-14, jobs in manufacturing declined, but by only 0.3% per year on average or around a tenth of the pre-downturn trend.

Across the whole economy, average hours worked per job increased between 2010 and 2013 and have been fairly flat since then at around 31 hours per week, a level last seen in 2007. The increase in average hours has been particularly pronounced in construction, where average hours worked in 2014 was the highest since 2002 and around 2 hours a week higher than in 2012. Average hours worked have also increased in manufacturing, and this combined with very low rates of job losses noted above means that hours worked in manufacturing have been more or less flat since Q1 2009, following decades of declines.

UK economic output is estimated to have increased at an average rate of around 0.7% per quarter since the start of 2013. Output of the production industries has grown a little below the whole economy figure, and output of market services has grown a little faster.

The impact of measured movements in hours worked and economic output on productivity is summarised in Figure 1, which de-composes movements in output per hour since Q1 2008 in terms of cumulative quarterly changes. Output per hour was around 1% lower in Q1 2015 than in Q1 2008. This is entirely accounted for by industries ABDE (non-manufacturing production and agriculture) and by financial services.

The weakness of productivity in these sectors (which can to some extent be rationalised in terms of resource depletion in the oil and gas extraction industry and increased regulation in financial services) should not detract from what is otherwise exceptionally weak productivity in other industries. Output per hour in services other than financial services has grown by around 0.2% per quarter since the bottom of the economic downturn in Q1 2009, compared with trend productivity growth of around 0.5% per quarter prior to the downturn. And output per hour in manufacturing has expanded at an average quarterly rate of around 0.3% since Q1 2009, compared with almost 1% per quarter prior to the downturn.

Figure 2 shows the progression of ULC changes since Q1 2008, with each period representing growth on the quarter from the prior year. The bars represent the decomposition of ULC changes into changes in total labour costs per hour and changes in output per hour, which has been reversed so a negative bar represents positive productivity growth.

The growth of unit labour costs at the whole economy level remains subdued, as the upturn in growth of labour remuneration per hour (broader than, but correlated with, conventional measures of labour earnings such as average weekly earnings (AWE)) has broadly matched the gradual acceleration of labour productivity noted above. More recent data for the three months Feb-Apr 2015 indicate a further pick-up in AWE, but it is too early to say whether this will convert either into the broad labour remuneration concept used in compiling ULCs, or indeed whether this upturn could herald an upturn in productivity growth.

Figure 3 shows trends in ULCs by broad industry, based on experimental estimates available in a Reference Table (261.5 Kb Excel sheet) component of this release. Note that the manufacturing ULC series shown in Figure 3 differs in coverage and methodology from the manufacturing unit wage cost series shown in Table 2 of the pdf version of this release. Variation in ULC evolution by industry mainly reflects variation in productivity trends, as movements in labour remuneration tend to be closely correlated across industries. For example, since 2008 hourly labour remuneration has grown by around 2% per year in manufacturing and the broader production industries. Yet ULCs have grown faster in the production industries than in manufacturing, reflecting weak productivity in the non-manufacturing components.

Notes for General commentary

  1. Employment growth in 2014 is likely to be revised up slightly when new population estimates are incorporated into the LFS estimates in early 2016.

Whole economy labour productivity measures

The whole economy output per hour estimate for Q1 2015 continued a gradual upward trend, with an increase on the year and on the quarter (shown in figure 4). Output per hour is still below its Q1 2008 level and its post crisis peak in Q3 2011.

Productivity growth is stronger when considered on an output per job basis. This difference suggests those who are employed are working longer hours and this is reflected in the strong growth of hours relative to jobs and output since mid-2011 (see figure 5), though the difference has narrowed slightly in the latest quarter.

Quarter on quarter growth in market sector output per worker (not a National Statistic) has lagged that of the whole economy for the past two years. Yet the measure has grown faster than market sector output per hour (also not a National Statistic), suggesting that the market sector is following the same trend as the whole economy with workers putting in more hours.

On a per hour basis, market sector productivity has more closely tracked that of the whole economy over the past year (see figure 6).

Manufacturing labour productivity measures

Manufacturing output per hour has fallen 0.8% in Q1 2015 compared to a year earlier as most industry groups (with the exception of the chemical and pharmaceutical industry, group 20-21) have moved from a positive productivity performance to a negative one (see figure 7).

In recent periods, the metals and non-metals industries (group 22-25) has seen the largest fall in output per hour from a year prior, though productivity in this industry has been relatively volatile for the past couple of years. The machinery and equipment industry group (which includes computer products, and electrical and transport equipment) performed relatively well after the initial downturn, but in the most recent quarter the group saw the largest fall in output per hour to the prior year.

The overall fall in manufacturing productivity is down to labour inputs (in terms of hours and jobs) recently growing at a steady pace while GVA growth is flattening out, as shown in figure 8. GVA grew in 2013 after the post crisis recovery stumbled in 2011 and 2012, though growth has been slower since the start of 2014, while jobs growth (and more recently, hours growth) have picked up.

More information on the labour productivity of sub-divisions of manufacturing is available in Reference Table LPROD01 (362 Kb Excel sheet) (Tables 3 and 4), and in the tables at the end of the pdf version of this statistical bulletin. Care should be taken in interpreting quarter on quarter movements in productivity estimates for individual sub-divisions, as small sample sizes of the source data can cause volatility.

Tables 3 and 4 include annual estimates for the level of productivity in £ terms for the National Accounts base year of 2011. These are estimates of GVA per unit of labour input and are not necessarily related to pay rates. Output per job (Table 3) varied from £39.2k in Wood and paper products (divisions 16-18) to £134.4k in Chemicals & Pharmaceuticals (divisions 20-21). The average for the whole of manufacturing was £57.4k and the average for the whole economy was £47.2k in 2011.

Chemicals & Pharmaceuticals was also top of the distribution for output per hour in 2011 (£75.0), with Wood, paper products, & printing (divisions 16-18) at the bottom of the distribution (£21.6). On this basis the average for manufacturing as a whole was £31.0 and the average for the whole economy was £29.9 per hour.

Services labour productivity measures

Services output per hour growth on the quarter from a year prior has remained positive since 2014 Q3, which is in contrast to six quarters of negative growth for this measure from Q2 2012 (see figure 9).

Productivity growth has returned to the government services industry (O-Q), while professional and admin services (M-N) returned negative productivity growth on a year prior in Q1, despite a positive performance in much of the post-crisis period. The retail industry has recently performed well in terms of output per hour from the previous year, recovering from four weak periods from 2012 Q2.

GVA has grown steadily since mid-2009 (see figure 10), while jobs have grown at a slower pace. This has resulted in stronger output per job growth to that of output per hour since Q4 2011.

More information on labour productivity of services industries is available in  Tables 5 and 6 of Reference Table LPROD01 (362 Kb Excel sheet) and in the tables at the end of the pdf version of this statistical bulletin.

In general, the dispersion of labour productivity growth rates across service industries is less pronounced than within manufacturing. But the dispersion of productivity levels is more pronounced. Yet, it should be borne in mind that labour productivity in industry L is affected by the National Accounts concept of output from owner-occupied housing, which adds to the numerator but without a corresponding component in the denominator. Excluding this industry, output per job in 2011 varied from £21.6k in Accommodation & food services (section I) to £106.5k in Finance & insurance (section K). These industries were also at the bottom and top of the productivity distribution in terms of output per hour (Table 6).

Industry spotlight - Information and communication services industry

The Information and communication services industry (industry J) consists of six divisions:

  • Publishing activities (division 58)
  • Motion picture, video and television programme production, sound recording and music publishing activities (59)
  • Programming and broadcasting activities (60)
  • Telecommunications (61)
  • Computer programming, consultancy and related activities (62)  
  • Information service activities (63)

Annual output per hour for industry J saw a large boost in the late 1990s and early 2000s, driven by high output growth rates. Figure 11 shows this boost, with a decomposition of productivity into annual changes in output (represented by the lighter bars) and hours worked (the darker bars). The hours worked data are reversed, so a negative bar denotes an increase in hours worked, in order to show the effect changes have had on labour productivity.

Growth of output per hour for industry J has trended downwards since 2003, though it has been more volatile since 2009. The downward trend, in recent years, has been due to low output growth and annual increases in hours worked, which have kept productivity growth negative for three out of four quarters.

When looking at total hours worked for industry J, computer programming and consultancy (division 62) accounted for approximately 52% of the total in 2014 (see figure 12). Telecommunications was the second largest component, accounting for roughly 17% of total hours worked in 2014. The proportion of hours worked allocated to each division of industry J has stayed relatively stable over time, with computer programming and consultancy maintaining the largest share.

Output in industry J followed a similar trend, with computer programming and consultancy maintaining the largest share amongst the six components. It accounted for approximately 52% of total output in 2014. The second largest component, telecommunications, accounted for approximately 24% of the total.

Figure 13 shows indexed output per hour growth rates for the six components of industry J. Telecommunications is shown on the right hand scale, while all other divisions are represented on the left hand scale.

The figure shows that telecommunications has outperformed industry J’s other components in terms of output per hour by a significant margin. Productivity for telecommunications grew by about 13% a year, on average, from 1997 to 2008, and appeared to recover after a pro-cyclical dip in 2009. But output per hour then fell in each of 2012, 2013 and 2014. 

Output per hour for computer programming and consultancy, the largest division of industry J, grew by 5% a year, on average, from 1997 to 2008, but since 2008 its performance has been relatively flat.

Revisions

The Revisions table in Reference Table LPROD01 (362 Kb Excel sheet) shows revisions to growth rates of the main productivity estimates for the whole economy and selected sub-industries between this release and the previous release on 1 April 2015.

On the output side, GVA estimates have been revised back to Q1 2014, including revisions to construction estimates arising from the introduction of an interim solution for construction price indices. Compared with the last Labour Productivity release on 1 April 2015, quarterly construction GVA has been revised upwards by up to 4.2% on a quarterly basis, and by 1.9% in 2014. GVA as a whole has been revised up by 0.2% in 2014.

On the input side revisions reflect the outcome of the periodic review of seasonal adjustment parameters applied to jobs and hours estimates. This has had only a limited impact on jobs. But the review of hours has also introduced adjustments to align the LFS 13-week sampling frame with calendar quarters. This has led to extensive changes to seasonally adjusted hours estimates, even where seasonally adjusted jobs estimates are unchanged. This process also introduces material differences between calendar year averages of seasonally adjusted quarterly estimates and their non-seasonally adjusted (NSA) counterparts. For example, NSA total hours worked are estimated to have grown by 2.0% in 2012 and by 1.8% in 2013, while the new seasonally adjusted series shows growth of 1.4% in 2012 and 2.4% in 2013. Differences between NSA and seasonally adjusted calendar year totals are also a feature of the published LFS aggregate hours series. But users should note that differences at the aggregate level between hours estimates used in this release and the LFS published aggregate are somewhat larger than in recent editions of this release.

A research note on sources of revisions (145.4 Kb Pdf) to labour productivity estimates is available on the ONS website.

Table A below summarises differences between first published estimates for each of the statistics in the first column with the estimates for the same statistics published three years later. This summary is based on five years of data, that is, for first estimates of quarters between Q2 2007 and Q1 2012, which is the last quarter for which a three-year revision history is available. The averages of these differences with and without regard to sign are shown in the right hand columns of the table, and these can be compared with the value of the estimates in the latest quarter, shown in the second column. Additional information on revisions to these and other statistics published in this release is available in the Revisions Triangles (1.69 Mb Excel sheet) component of this release.

Table A: Revisions

Revisions between first publication and estimates five years later (Q2 2007 - Q1 2012)

Output per worker 1.0 0.0 0.9
Output per job 0.9 0.0 0.8
Output per hour 1.3 0.0 0.7
Unit labour costs 0.9 0.0 1.3
Unit wage costs 2.2 -0.2 1.2

Download table

This revisions analysis shows that whole economy labour productivity growth estimates have tended to be unrevised over time (on a year-on-year basis). Unit labour costs have also been unrevised, while unit wage costs have tended to be revised down by 0.2 percentage points. Were the average revisions to apply to the current release, growth of output per hour in the year to the first quarter of 2015 would be unrevised at 1.3% over the next three years. Growth of unit labour costs would also be unrevised from 0.9%, while growth of unit wage costs would be revised from 2.2% to 2.0% over the same period.

Notes on sources

The measure of output used in these statistics is the chain volume (real) measure of Gross Value Added (GVA) at basic prices, with the exception of the regional analysis in Table 9, where the output measure is nominal GVA (NGVA). These measures differ because NGVA is not adjusted to account for price changes; this means that if prices were to rise more quickly in one region than the others, then this would be reflected in apparent improved measured productivity performance in that region relative to the others. At the whole economy level, real GVA is balanced to other estimates of economic activity, primarily from the expenditure approach. Below the whole economy level, real GVA is generally estimated by deflating measures of turnover; these estimates are not balanced through the supply-use framework and the deflation method is likely to produce biased estimates. This should be borne in mind in interpreting labour productivity estimates below the whole economy level.

Labour input measures used in this bulletin are known as 'productivity jobs' and 'productivity hours'. Productivity jobs differ from the workforce jobs (WFJ) estimates published in Table 6 of the ONS Labour Market Statistics Bulletin, in three ways:

  • To achieve consistency with the measurement of GVA, the employee component of productivity jobs is derived on a reporting unit (RU) basis, whereas the employee component of the WFJ estimates is on a local unit (LU) basis. This is explained further below.

  • Productivity jobs are scaled so industries sum to total LFS jobs. Note that this constraint is applied in non-seasonally adjusted terms. The nature of the seasonal adjustment process means that the sum of seasonally adjusted productivity jobs and hours by industry can differ slightly from the seasonally adjusted LFS totals.

  • Productivity jobs are calendar quarter average estimates whereas WFJ estimates are provided for the last month of each quarter.

Productivity hours are derived by multiplying employee and self-employed jobs at an industry level (before seasonal adjustment) by average actual hours worked from the LFS at an industry level. Results are scaled so industries sum to total unadjusted LFS hours, and then seasonally adjusted.

Industry estimates of average hours derived in this process differ from published estimates (found in Table HOUR03 in the Labour Market Statistics release) as the HOUR03 estimates are calculated by allocating all hours worked to the industry of main employment, whereas the productivity hours system takes account of hours worked in first and second jobs by industry.

Whole economy unit labour costs are calculated as the ratio of total labour costs (that is, the product of labour input and costs per unit of labour) to GVA. Further detail on the methodology can be found in Revised methodology for unit wage costs and unit labour costs: explanation and impact.

Manufacturing unit wage costs are calculated as the ratio of manufacturing average weekly earnings (AWE) to manufacturing output per filled job. On 28 November 2012 ONS published Productivity Measures: Sectional Unit Labour Costs describing new measures of unit labour costs below the whole economy level, and proposing to replace the currently published series for manufacturing unit wage costs with a broader and more consistent measure of unit labour costs.

What is a reporting unit?

The term 'enterprise' is used by ONS to describe the structure of a company. Individual workplaces are known as 'local units' and a group of local units under common ownership is called the 'enterprise'. In ONS business surveys, reporting units are the parts of enterprises that return data to ONS. While the majority of reporting units and enterprises are the same, larger enterprises have been split into reporting units to make the reporting easier.

For most business surveys run by ONS, forms are sent to the reporting unit rather than local units, in other words, to the head office rather than individual workplaces. This enables ONS to gather information on a greater proportion of total business activity than would be possible by sending forms to a selection of local units. But it has the disadvantage that it is difficult to make regional estimates – for instance all the employment of, say, a chain of shops would be reported as being concentrated at the site of the head office.

Further differences between reporting unit and local unit data can be seen in the industry coding. Take, for example, a reporting unit with three cake shops and one bakery, each employing five people. The local unit analysis would put 15 employees in the retail industry and five employees in the manufacturing industry. But the reporting unit series puts all 20 people into the industry with the majority activity, in this case, retailing. Detailed industry figures compiled using the local unit approach will therefore be different from industry figures using the reporting unit approach, although the totals will be the same at the whole economy level.

Background notes

  1. This statistical bulletin

    This statistical bulletin presents Labour Productivity estimates for the UK. More detail can be found on the Productivity Measures Topic page on the ONS website.

    Index numbers are referenced to 2011=100, are classified to the 2007 revision to the Standard Industrial Classification (SIC) and are seasonally adjusted.

    Quarter on previous quarter changes in output per job and output per hour worked for some of the manufacturing sub-divisions and services sections should be interpreted with caution as the small sample sizes used can cause volatility.

  2. Quality and Methodology

    A revised and updated Quality and Methodology Information paper (649 Kb Pdf) for Labour Productivity was published in March 2012. This paper describes the intended uses of the statistics presented in this publication, their quality and methods used to produce them. It also includes more information on the uses and limitations of labour productivity estimates.

  3. Future developments

    ONS published ' Productivity measures and analysis: ONS work plan (241 Kb Word document) ' in February 2015, reviewing developments since the last productivity workplan was published in 2006 and setting out priorities for future work. Although this was not a formal consultation document, ONS welcomes feedback from users, which can be sent to productivity@ons.gsi.gov.uk.

    In 2012 ONS developed new and improved measures of labour input as part of ongoing work to comply with EU regulations. Specifically, these new measures provide an industry breakdown of employment (i.e. on a headcount basis rather than a job basis), and provide a split between employees and the self-employed. For methodological consistency, this work has also made some changes to the computation of corresponding hours series. These series are currently available on the Eurostat website and ONS has published an article entitled Introducing New Labour Productivity Statistics which describes these new series.

    In response to user requests, ONS has now published selected estimates of labour productivity using the new and improved estimates of labour inputs, together with comparisons against the corresponding estimates from the existing productivity system. These are available as an additional reference table component (table NEWLPROD01) of the aforementioned article.

  4. Other data on productivity

    ONS has published Labour Productivity Measures from the ABS, 2008-2012. This article uses published estimates from the Annual Business Survey (ABS) to provided more detailed information on recent trends in labour productivity by industry than those available from other sources.

    ONS publishes International comparisons of labour productivity in levels and growth rates for the G7 countries.

    More international data on productivity are available from the OECD, Eurostat, and the Conference Board.

    ONS publishes experimental estimates of Multi-factor productivity (MFP), which decompose output growth into the contributions that can be accounted for by labour and capital inputs. In these estimates, the contribution of labour is further decomposed into quantity (hours worked) and quality dimensions.

    ONS also publishes experimental indices of labour costs per hour. These differ from the concept of labour costs used in the unit labour cost estimates in this release. The main difference is that experimental indices of labour costs per hour relate to employees only, whereas unit labour costs also include the labour remuneration of the self-employed.

    Lastly, ONS publishes a range of Public sector productivity measures and related articles. These measures define productivity differently from that used in the ONS labour productivity and MFP estimates. Further information can be found in Phelps (2010) (252.5 Kb Pdf)  and in an ONS Information Note (433.2 Kb Pdf) published on 4 June 2015.

    More information on the range of ONS productivity estimates can be found in the ONS Productivity Handbook.
