How do full-time-equivalent rates change the picture of UK labour-market slack?. Structure the report around the FTEER and FTEUR definitions, then compare them with conventional UK employment and unemployment rates. Include a table of gender, age, qualification, regional, and local economic findings, followed by a limitations section on the 37.5-hour benchmark, desired-hours assumptions, sampling error, and non-causal correlations.

How FTE rates change the picture of UK labour-market slack

Full-time-equivalent measures show that the UK labour market used fewer hours, and contained more unused labour, than conventional person-based rates suggest. For 2016–18, the FTE employment rate (FTEER) was 63.6%, compared with a conventional employment rate of 74.6%; the FTE unemployment rate (FTEUR) was 9.1%, compared with conventional unemployment of 4.6%.[1] The central implication is not that conventional indicators are wrong, but that they answer a different question: conventional rates count people, while FTE rates quantify hours actually worked and additional hours wanted.[2]

FTEER: measuring employment in hours

The full-time-equivalent employment rate is defined as total hours worked per week divided by 37.5 multiplied by the working-age population. The 37.5-hour benchmark represents assumed normal full-time weekly hours in the UK, converting total hours into a full-time-equivalent number that can be expressed as a percentage of the working-age population.[3][4]

FTEER gives greater weight to the amount of work performed than to the mere presence of an employment relationship. It includes all hours actually worked, including hours worked by people who would prefer to work fewer hours.[5] Because a person working one hour counts as employed under the conventional measure, but contributes only a small number of hours to FTEER, FTEER cannot exceed the conventional employment rate.[6][7]

FTEUR: measuring underutilised labour in hours

The full-time-equivalent unemployment rate is the total additional hours wanted by unemployed and underemployed people divided by total potential hours. Total potential hours are defined as hours currently worked plus additional hours wanted.[8] This combines people without work who are seeking employment with employed people who are actively seeking more hours, thereby measuring the volume of labour underutilisation rather than simply the number of unemployed people.[9]

FTEUR does not subtract overemployment. The article treats hours already being worked as part of current labour supply and notes that overemployed people are not measured as seeking fewer hours in a directly comparable way.[10] Unlike FTEER, FTEUR does not require a normal full-time-hours benchmark, but it does require an estimate of the hours unemployed people would like to work.[11] Since it includes wanted hours among both unemployed and underemployed people, FTEUR cannot be lower than the conventional unemployment rate.[12][13]

FTE measures compared with conventional UK rates

IndicatorWhat it countsWhat it reveals about slack
Conventional employment ratePeople of working age who are employed. Under the ILO definition used in the article, working for just one hour in the reference week is sufficient to count as employed.[14]Shows the prevalence of employment, but gives equal status to very different amounts of work.
FTEERTotal hours actually worked, scaled by 37.5 hours and the working-age population.[15][16]Shows how much full-time-equivalent labour is actually being used, making part-time work and short hours visible.
Conventional unemployment rateUnemployed people as a proportion of the workforce. It excludes employed people who are seeking additional hours.[17]Shows joblessness among the active workforce, but excludes underemployment.
FTEURWanted additional hours among unemployed and underemployed people as a share of worked plus wanted hours.[18]Shows the wider volume of unused labour among the active workforce. It excludes economically inactive people who want a job, because the measure is designed to remain comparable with active-workforce employment and unemployment definitions.[19]

The UK comparison illustrates the scale of the adjustment. A conventional employment rate of 74.6% becomes an FTEER of 63.6%, an 11-percentage-point reduction. Conventional unemployment of 4.6% becomes FTEUR of 9.1%, approximately twice as high.[20] Part-time work and underemployment therefore make conventional indicators look stronger than the underlying volume of labour utilisation warrants.

Who and where experiences the largest gaps?

The article finds that FTE measures particularly alter the picture for women, younger workers and people with low or no qualifications. They also change regional rankings and reveal local economic relationships that are weak or absent when conventional rates are used.[21]

DimensionFinding from conventional ratesWhat the FTE measures add or change
GenderWomen’s conventional employment rate is just under 70%.[22] Conventional unemployment produces the opposite gender pattern from FTE unemployment.[23]Women’s FTEER is just under 51%, nearly 19 percentage points below their conventional employment rate.[24] Women have greater unemployment than men on the FTE measure, and women’s FTEER is lowest in predominantly rural areas, unlike their conventional employment rate, which is lowest in predominantly urban areas.[25][26]
AgeWorkers aged 18–24 have conventional unemployment of just under 11%.[27]Youth FTEUR is nearly 20%, almost twice the conventional rate.[28] Scotland has the largest youth employment-rate shortfall, while the region with the highest youth unemployment changes from London on the conventional measure to Wales on the FTE measure, where FTE youth unemployment is 22.4%.[29][30]
QualificationPeople with no qualifications have conventional unemployment of just over 9%.[31]Their FTEUR is almost 15%, around six percentage points higher, while their FTEER is only 37%.[32][33] The East Midlands shifts from above to below the UK average for low-skilled employment when FTEER is used; London and the East Midlands also shift from below to above average for low-skilled FTE unemployment.[34][35]
RegionsConventional rankings identify the North East as having the highest unemployment rate.[36]The largest all-worker employment gaps are in Scotland, the South West and Wales. London has the smallest employment gap and is the only region to move from below to above the UK average on FTEER, reflecting more full-time jobs and longer hours. The highest unemployment changes to London on the FTE measure.[37][38]
Local economiesConventional employment is not correlated with workplace hourly pay or jobs density.[39]FTEER is correlated with median and lower-quartile hourly pay and with jobs density, while neither conventional nor FTE unemployment is correlated with those variables.[40][41] Across 179 NUTS3 areas, FTE and conventional rates are generally less closely aligned for women, young people and low-skilled workers, indicating different local spatial patterns.[42]

Limitations and interpretation

  • The 37.5-hour benchmark: Full-time hours vary by occupation, industry and employer, and flexible contracts make a single normal week ambiguous. Using average hours of self-described full-time workers could also overstate normal hours if those workers include excessive hours.[43] Comparisons across countries or long periods are consequently sensitive to different full-time norms and changing working-time patterns.[44]
  • Desired-hours assumptions: The Labour Force Survey asks employed people about additional hours wanted, but asks unemployed people whether they seek full-time or part-time work rather than their precise desired hours.[45] The article therefore imputes unemployed people’s desired hours using the mean hours worked plus extra hours wanted among employed people, despite differences between the two groups in skills, age and occupation.[46]
  • Sampling error: Although the analysis covers all 179 UK NUTS3 localities, the estimates are built from Annual Population Survey microdata based on sampled residential addresses. Regional estimates and correlations therefore remain subject to sampling error, with confidence intervals indicating sensitivity to changes in the data.[47]
  • Non-causal correlations: The local analysis uses simple correlations and is exploratory. An association between FTEER, pay and jobs density does not establish that pay or labour demand causes higher labour utilisation, or identify the direction of causation.[48]
  • Overemployment: FTEUR does not subtract hours that overemployed workers would prefer to give up. That is appropriate for measuring current and potential labour supply, but not for measuring the match between actual and preferred hours.[49]

These limitations mean that FTE rates should be read as informative complements rather than mechanically superior replacements. Their value is greatest when the question concerns the amount of labour being used or available, especially where part-time work, short hours and underemployment are unevenly distributed across groups and places.[50][51]

Conclusion

FTEER lowers the apparent strength of UK employment by translating jobs into hours, while FTEUR raises apparent unemployment by adding the unused hours sought by underemployed workers. The resulting picture is of substantially more labour-market slack than conventional rates show, with especially large differences for women, young people, low-qualified workers and several peripheral regions.[52][53]

Conventional rates remain useful for tracking how many people have jobs or are unemployed. FTE rates answer the complementary policy question: how much labour is actually being deployed, and how many additional hours could the active workforce supply? The measures should therefore be reported together, with explicit sensitivity analysis around the full-time-hours benchmark, desired-hours imputation and survey uncertainty.
