Statistics for small areas (below local authority level) and on specific population characteristics were not published in the first Census 2021 release.  

Later publications

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

Census statistics for small areas, including wards and statistical geographies, are also available with data for areas in Swansea included in the following pages:

• Area Profiles: includes Census data on population characteristics (country of birth, ethnic group, ability to speak Welsh, general health, disability, qualifications); household composition and size; accommodation type; housing tenure; economic activity status.  Profiles are available for Swansea's electoral wards and constituency areas.  Area Profiles
• Households (with residents); usual residents living in households and communal establishments; average household size.  Household estimates - Local statistics
• Population estimates by age and population density data based on the 2021 Census is also available.  However, these pages have now been updated to include the latest statistics in each case, which are currently for mid 2022.

We intend to include further local statistics, information and analysis of data from the 2021 Census on our pages in due course.
