The Department for Business, Energy and Industrial Strategy (BEIS) is responsible, with the Office for National Statistics (ONS) for publishing the National Statistics on trade union membership.
Estimates are presented for the proportion of people in employment who are trade union members in both the UK and Great Britain, and for employees whose pay and conditions are affected by collective agreements. We also provide trade union densities by age, sex, ethnicity, income, full and part-time employment, sector, nation and region.
Earlier trade union membership publications are available from The National Archives, but can also be obtained from BEIS by contacting us.
The report is an annual publication and its timing is predetermined and pre-announced in accordance with the arrangements for releasing National Statistics.
Information on National Statistics, the labour market as well as relevant data can be obtained from the ONS website.
