Please provide a dataset giving the number of people in employment by age group, sex and employment status. I would like the information going as far back as possible, ideally to 1994.

Thank you for your query regarding employment statistics.

Estimates of the number of people in employment by various characteristics are available from the Labour Force Survey (LFS).

We produce statistics of employment by age group and sex. We also have statistics by employment status and sex. However, we do not routinely produce statistics from the LFS that combine all these elements. Both these outputs have statistics back to 1992.

Employment status by sex

Estimates for more detailed breakdowns are available from the Annual Population Survey (APS). This is an annualised version of the LFS, based on certain LFS interviews, plus additional boost interviews.

We produce an explorable dataset on our Nomis website, which allows you to extract information by employment status, age group and sex. You will need to make the selections you require from the dataset, but then can extract the requested information in spreadsheet format. However, the APS only has information from 2004 onwards.
