Small area annual population estimates

Population estimates for small areas in Swansea are published by the Office for National Statistics (ONS).

The latest data (for mid-2020) is available for Electoral Wards and Super Output Areas in Swansea. Lower layer Super Output Area (LSOAs) are statistical reporting units developed by ONS with a minimum population of 1,000 (current average 1,620). Middle layer Super Output Areas (MSOAs) are built from groups of adjacent LSOAs and have a minimum population of 5,000 (average 7,800). 

Summary local population estimates for 2020 are available from this page. The  LSOA [354KB] MSOA [723KB]  and  Ward [340KB]  level data for areas in Swansea is shown on the basis of the broad life stage groups: children (0-15), working age (16-64) and older people (65+).  An additional file provides the latest Ward, MSOA and LSOA data in Swansea by single year to enable  further calculations [347KB] .  Map images on this page also show the broad location of the 31  MSOAs in Swansea [4MB]  and 36  Electoral Wards [2MB]  in Swansea.  Individual maps of Swansea's Wards and Super Output Areas are also available via separate web pages.
