2021 Census: first results

The first census results for local authority areas in England and Wales were published by the Office for National Statistics (ONS) on 28 June 2022.

The 2021 Census reported that the usually resident population of Swansea was 238,500; approximately 500 or 0.2 per cent less than the 2011 Census total.

Over one in five (22 per cent, 52,600) of Swansea residents were aged under 20, with around 21% (48,900) aged 65 and over.

A summary briefing note (PDF) [1007KB] detailing the first 2021 Census results for Swansea is available on this page.  A supplementary briefing note is also available (PDF) [860KB], including information from the first results on households; population density; components of the estimates; response rates; on-line responses; and links to initial ONS reports.  Further information and analysis will follow as additional data is published.

Background information about the 2021 Census, including links to the ONS Census website, is available here.

Statistics for small areas (below local authority level) and on specific population characteristics were not published in the first Census 2021 release.   However, Census statistics for small areas including wards and statistical geographies are now available with data for areas in Swansea included in the following pages:

  • Population by age
  • Population density
  • Households (with residents); usual residents living in households and communal establishments; average household size.

ONS have also since published Topic Summary data from the 2021 Census on a range of population and household characteristics.

Further information and analysis of data from the 2021 Census will be added to these pages as soon as possible.
