Quality-adjusted UK public service productivity fell by 15.2% in 2020, largely because of the effect of the coronavirus (COVID-19) pandemic, after a small decline in the previous year.
Total quality-adjusted output fell by 7.4% in 2020, as the pandemic caused a delay to some public service activities and changes to the delivery of others.
Total inputs grew by 9.2% in 2020, with additional resourcing required to respond to the pandemic.
Healthcare and education were the main contributors to the fall in productivity (down 23.0% and 26.1% respectively): healthcare output fell by 6.6%, while inputs rose considerably (21.2%); education output fell considerably (26.4%) because of the impact of remote learning and student absences, while inputs remained roughly steady (down 0.4%).
This article includes updated estimates of non-quality-adjusted (NQA) and quality-adjusted (QA) output, inputs and productivity for nine public service areas, in the UK between 1997 and 2020. All these statistics are measured on a calendar year basis.
Public service inputs grew by 9.2%, and output fell by 7.4% in 2020 compared with the previous year. As a result, public service productivity on a quality-adjusted basis fell sharply by 15.2%. Excluding quality adjustments to outputs, public service productivity fell by 13.9%.
Caution should be used when comparing latest estimates with those pre-coronavirus , as many services were delivered in a different way than in 2019, with additional inputs necessary and mandatory restrictions limiting output for certain services.
Inputs growth in 2020 was the highest recorded since the beginning of the data series in 1997. This reflects the extra resources required and provided to produce public services as a result of the coronavirus (COVID-19) pandemic.
Total public service output and inputs are calculated by aggregating output and inputs of nine service areas based on their share of expenditure, as explained in our methods article. A larger expenditure share means that the service area has a larger contribution to the overall productivity statistic. The largest expenditure shares were:
"other" government services (16.0%): general government services, economic affairs, environmental protection, housing, recreation, and other public order and safety
The contributions to growth in Figure 4 reflect the productivity growth for the service areas measured directly, weighted by their expenditure share each year. Healthcare had the largest negative contribution to public service productivity in 2020 (negative 9.6 percentage points), followed by education (negative 4.1 percentage points) and adult social care (negative 1.1 percentage points). These areas all saw increased resourcing and restrictions to what they could deliver because of the pandemic.
Police, defence and "other" government services are not included in Figure 4, since they are measured using the "output-equals-inputs" convention where productivity growth is always zero.

Healthcare represents the largest service area included in public service productivity estimates by expenditure share (around 41.4% of total public service provision).
Public service healthcare productivity fell sharply by 23.0% in 2020 on a quality-adjusted basis, the most significant one-year fall in productivity since the start of the data series. This was driven by growth in inputs of 21.2% and output falling 6.6%.
Excluding quality adjustments to outputs, public service healthcare productivity fell by 23.5% in 2020, reflecting a fall in non-quality adjusted output growth of 7.2%.
Caution should be used when comparing latest estimates with those pre-coronavirus as some non-urgent services were stopped to reduce the spread of COVID-19 and any healthcare benefits from these decisions compared with a hypothetical case where services were not reduced are difficult to measure.
While the figures in Figure 5 are calculated on a calendar year basis, most of the data used in healthcare productivity are produced using financial year data. As a result, falls in output in the financial year ending 2021 may have some effect on the 2020 figures.Nôl i'r tabl cynnwys
Education is the second largest service area in public service productivity by expenditure share.
UK education services productivity fell sharply by 26.1% in 2020 on a quality-adjusted basis. This was driven by a fall in output of 26.4% and relatively stable inputs growth of negative 0.4%.
Excluding quality adjustments to outputs, education services productivity fell by 17.2% in 2020, reflecting a fall in non-quality adjusted output growth of 17.5%.
Quantity output fell by 17.5% in 2020, largely because of the impact of remote learning on teaching hours, teaching materials provided and increased sickness rates as a result of coronavirus. This was estimated in a similar way to national accounts estimates but differs somewhat because of slight differences in the coverage and source data used to compile productivity estimates.
When the quality adjustment is taken into account, total output in 2020 fell even further (26.4%). While some data on teacher assessed attainment were available in 2020, this was not used to determine the quality of education given that it was not comparable with non-teacher assessed attainment data. Instead, research from the Department for Education and Education Policy Institute (EPI) on pupil learning loss was used to develop a proxy measure for educational attainment in 2020. Our proxy measure assumes that were pupils assessed as normal in 2020, attainment would have fallen because of the significant learning loss as quantified in the EPI reports. Adjustments for bullying and the disadvantage gap have not been included for 2020 because of a lack of comparable data.
Because of the use of proxy data these estimates should be treated with caution. The evidence for a fall in education output in 2020 is strong, however, the accuracy of these estimates is affected by the lack of non-teacher assessed examinations in 2020.Nôl i'r tabl cynnwys
Public order and safety (POS) includes a range of services. Where applicable, output is also adjusted for quality.
POS productivity fell by 13.3% in 2020 on a quality-adjusted basis. This was driven by growth in inputs of 4.7% and a fall in quality-adjusted output of 9.2%. A reduction of activity and slowdown of case completion within the courts system was the main contributor to the fall in output. Restrictions to deal with the coronavirus (COVID-19) pandemic contributed to these falls.
Inputs and output growth were somewhat steadier within the Fire and Rescue Service. Prisons output also remained approximately steady, with improved overall safety offsetting a fall in the prison population.
Changes to how prisons operated as a result of the pandemic have probably affected prison safety statistics. While there were increased deaths because of natural causes, these were offset by reductions in other deaths and injuries as well as fewer escapes. Inputs within the prisons service increased.
Reoffending data are not included in the quality adjustment in 2019 and 2020. Data on proven reoffending have been affected by the coronavirus (COVID-19) pandemic and are no longer comparable with the previous year, as explained in the 2019 article.Nôl i'r tabl cynnwys
Police, defence and "other" government services are three sectors in which all output is indirectly measured.
Of these, only inputs into police grew in 2020, by 6.2%, the first positive increase in five years. Inputs into defence and "other" government services fell marginally, by 0.9% and 0.4% respectively.

Inputs, output and productivity ind
These are services delivered by or paid for by government (central or local). If paid for by the government, they may be delivered by a private body -- for example, the provision of nursery places by the private sector, where these places were funded by the government.
Direct output measurement
Using a cost-weighted activity index to estimate the non-quality-adjusted of a service provided, such as the number of students in state schools, adjusted for attendance to produce an estimate of total hours of schooling delivered each year. Differs from indirect output measurement, where output is assumed equal to inputs.
A statistical estimate of the change in the quality of a public service, using an appropriate metric, such as safety in prisons as part of the public order and safety adjustment.
The Classification of the Functions of Government (COFOG) is the structure used to classify government activities. It is defined by the United Nations Statistics Division.
The way we refer to the breakdown of public services into nine areas, closely following COFOG.
Also referred to as "goods and services", or "intermediate consumption" (the UK National Accounts term). Intermediate inputs include goods and services used up in the provision of a public service, such as utilities, energy, professional services and medical supplies, among others.
A price index used to remove inflation effects from current price estimates of expenditure to provide a volume estimate.Nôl i'r tabl cynnwys
Productivity is the measure of how many units of output are produced from one unit of inputs. It is calculated by dividing total output by total inputs. Details of inputs and output can be found in the Sources and methods article.
Growth rates of output and inputs for individual service areas are aggregated by their relative share of total government expenditure (expenditure weight) to produce estimates of total public service output, inputs and productivity.
Service areas are defined by Classification of the Functions of Government (COFOG) rather than administrative departments or devolved administrations. As a result, estimates presented cannot be taken as direct estimates of departmental productivity. Lastly, it should be noted that these estimates do not measure, for example, the value for money in public services, or the true effectiveness of the services (quality adjustment includes some measurement of this but coverage is limited).
Estimates of public service productivity are published each year, and on a calendar year basis for consistency with the UK National Accounts. There is a two-year time lag associated with the estimates, because of the timeliness of our data, which come from administrative sources. This means that they meet certain quality criteria, listed in the Code of Practice from the UK Statistics Authority.
As explained in Section 2: The impact of the coronavirus (COVID-19) pandemic on public service productivity, the findings presented in this article were affected by the coronavirus (COVID-19) pandemic. A description of changes in methods because of the pandemic follows.
For output we have included, alongside the measures used in the previous years, the NHS Test and Trace and the COVID-19 vaccination programme, applying the same methods established for the UK National Accounts. These were new health services established to manage and mitigate the impact of COVID-19, and represent a sizeable contribution to public service healthcare output in 2020.
A quality adjustment, as in previous estimates, is applied to the quantity output. However, for 2020, patient experience and the aggregate data on clinical measures recorded on general practitioner (GP) practice computers (based on the quality and outcome framework) were excluded since these data are not available.
Data from Northern Ireland were not available for 2020, therefore Northern Ireland is not included in the weighting for the healthcare measure.
More information can be found in Section 9 of the Healthcare article.
Introduction of a discount rate to account for the impact of remote learning on teaching hours, teaching materials provided, and increased sickness rates as a result of COVID-19.
For quality adjustment, proxy data for attainment, sourced from research from the Department of Education and Education Policy Institute (EPI) has been used to approximate attainment had normal examinations taken place.
Adjustments for bullying and the disadvantage gap have not been included for 2020 because of a lack of comparable data.
Public order and safety
Reoffending data are not included in the quality adjustment in 2019 and 2020. Data on proven reoffending have been affected by the coronavirus (COVID-19) pandemic and are no longer comparable with the previous year, as explained in the 2019 article.
Social security and administration
Because of the introduction of Universal Credit in our data sources not yet being available, output estimates from 2018 onwards have become less robust. A new methodology taking advantage of more granular data on activities, costs and conditionality within the new benefits system will be developed in the future years by the ONS. In the meantime, an "output-equals-inputs" convention has been applied, fixing productivity at 0 until the improved data and methods are available.
Adult social care (ASC)
New output and input measures have been included for the devolved administrations. ASC input measures are produced using expenditure data from the respective administrations and deflators used in the England measure (which for intermediate consumption rely on UK-level price data) reweighted to reflect differences in the provision of care by local authority and independent-sector providers in the devolved administrations.
ASC output measures for Scotland have been updated since financial year ending (FYE) 2017 with a new measure, which includes residential care and home care on a directly measured (cost-weighted activity) basis and other services on an indirectly measured (deflated expenditure) basis using data from Public Health Scotland and the Scottish Government. For Northern Ireland, output is directly measured for services where activity data are available from the Northern Ireland Executive and indirectly-measured for the remaining services and for growth between FYE 2020 and FYE 2021 when activity data collection was discontinued. No activity data are available for Wales and so the output-equals-inputs approach is used for Wales.
Output and inputs for the four nations are weighted together using the implied expenditure from the respective measures for periods before FYE 2012 and using HM Treasury's Country and regional analysis data for subsequent years.
Different deflators for consumption of fixed capital have been used this year.Nôl i'r tabl cynnwys
