Small area population estimates

Population estimates for the years 2001 to 2010 for small areas in Swansea are currently published by the Office for National Statistics (ONS).

*** 2011 Census Update: the latest population figures at a small area level are the initial local area results from the 2011 Census. Local population statistics from the 2011 Census are available here. ***

Mid-2001 to mid-2010 data is available for Electoral Divisions or wards, and for '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 (average 1,500). Middle Layer Super Output Areas (MSOAs) are built from groups of adjacent LSOAs and have a minimum population of 5,000 (average 7,500). Unlike electoral wards, SOAs are of consistent size and less susceptible to boundary change.

Whilst the local estimates always sum to the equivalent local authority Mid Year Estimate total for each year, the methodology used to produce the local estimates differs from the method used to produce the local authority mid-year figures, and remains subject to further development. In view of this ongoing work, ONS currently publish the local population estimates as 'experimental statistics'.

The following local population estimates are available to view or download from this page:

• Electoral Divisions (wards) in Swansea, mid-2010
• Lower Super Output Area (LSOAs) in Swansea, mid-2010
• Middle Super Output Area (MSOAs) in Swansea, mid-2010.

The ward level population estimates are provided for the following selected age groups: 0-4, 5-15, 16-24, 25-44, 45-64, 65-74, 75+. LSOA and MSOA data is provided for the broad 'life stage' groups: children (0-15), working age (16-64) and older people (65+).

As an indicator of change since 2001, estimates of total population are also provided for the individual years up to 2010 (the latest data):

• Electoral Divisions (wards) in Swansea, 2001 to 2010
• Lower Super Output Area (LSOAs) in Swansea, 2001 to 2010
• Middle Super Output Area (MSOAs) in Swansea, 2001 to 2010.

The ONS small area population estimates are constrained to the latest published local authority population totals for each year.

Population estimates for other age group combinations are available on request. Please contact us.

Mid-2011 small area population estimates are currently scheduled for publication by ONS in April 2013 (for SOAs) and May-June 2013 (Wards). 

Note: Small area population estimates from the 2011 Census are now available here. Further information regarding the current ONS release schedule for 2011 Census data is available here.
