Population density

Statistics for Swansea and local geographies.

Population density estimates are available for Swansea and its local areas, including wards and Lower and Middle layer Super Output Areas (LSOAs and MSOAs).  These figures are derived by dividing the official mid-year population estimates by land area in square kilometres.  Land area is measured at mean high water mark and excludes areas of inland water, as recommended by the Office for National Statistics and Eurostat.

Population density figures (and supporting total population and land area estimates) are included in the file (Excel doc) [131KB] on this page, which contains the following separate worksheets:

  • City and County of Swansea, 1991 to mid-2022
  • Local authorities in Wales, mid-2022
  • Lower layer Super Output Areas in Swansea (LSOAs), mid-2022
  • Middle layer Super Output Areas in Swansea (MSOAs), mid-2022
  • Electoral wards in Swansea, mid-2022.

The average population density of the City and County of Swansea is 639 people per square kilometre (mid-2022 estimate), the fourth highest of the 22 local authority areas in Wales (average: 151 people per sq. km).  Within Swansea, local population density estimates vary considerably depending on the small area geography used:

  • For wards, values range from 32 people per square kilometre (for Gower ward) to 6,421 people per sq. km (Uplands ward).
  • MSOAs: from 49 people per sq. km (Swansea 030 - 'West Gower') to 8,897 people per sq. km (Swansea 026 - 'Brynmill').
  • LSOAs: from 29 people per sq. km ('Gower 2' LSOA) to 15,168 people per sq. km ('Uplands 9' LSOA).
