Population density

Statistics for Swansea and local geographies.

Population density estimates are available for Swansea and its local areas, namely Wards and Super Output Areas (lower and middle layer).  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.

The average population density of the City and County of Swansea is 653 people per square kilometre (2020 estimate), the fifth highest of the 22 local authority areas in Wales (average: 153 people per sq. km).  Within Swansea, ward-level population density estimates (2020) range from 32 (for the Gower and Mawr wards) to 6,693 people per sq. km (Uplands).
