The publication methodology explains the definitions used and how estimates have been produced. It also provides information on the data sources, their coverage and quality.
Coverage
The data used in this release mostly relate to the UK labour market and are aggregated together to create a UK demand index. The exception to this are indicators using data from the annual survey of hours and earnings, which does not contain data from Northern Ireland and is therefore Great Britain only.
The earliest data used in this release contains data to April 2022, the latest contains data to March 2024.
Information on how occupations or industries have been grouped together can be found in the additional supporting files of this release.
The underlying data files are provided in comma separated value (csv) format.
Rounding and decimal places vary across the different files, based on conventions for the relevant sources and what is appropriate for the analysis that has been undertaken.
Symbols used in the underlying data are as follows:
‘z’ when an observation is not applicable
‘x’ when data is unavailable for other reasons
‘c’ confidential data removed due to suppression

Some occupations from ONS’ job advert statistics were excluded from this analysis since the relative occupational distribution compared with annual population survey occupational data were judged in some cases to be relatively atypical. ONS plan to continue improving their statistics, including with an enhanced SOC allocation process, which may trigger revisions of the occupations excluded in future.
Only occupations which did not have any missing demand indicator data and were not otherwise excluded from the analysis were included in the clustering analysis, 268 out of 412 occupations.
Only four occupations were grouped into group 1. These occupations were grouped together because visa application density was their main demand indicator and this indicator was much higher than seen in all other occupations, indicating these occupations may react strongly to changes to visa rules.
The demand index covers a range of scores between -1.22 and 1.49.
Elected officers and representatives and senior officers in fire, ambulance, prison and related services are in critical demand due to a high wage premium and annual change in hours worked indicator respectively. However, data for these occupations is unavailable for three out of seven indicators and data is imputed from 3-digit SOC20 data for the remaining four. This also applies to three occupations in elevated demand: collector salespersons and credit agents, market and street traders and assistants, and visual merchandisers and related occupations. Care should be taken when considering the demand for these occupations.
