General description
This dataset provides population estimates for the lower layer (LSOAs), middle layer super output areas (MSOAs), upper layer super output areas (USOAs) and local authorities in Wales. These estimates are consistent with the results of the 2011 Census and are available for the 2011 LSOA, MSOA and USOA geographic boundaries published in October 2012.

Super output areas (SOAs) were introduced in 2004 to improve the reporting of small area statistics. They are built from groups of census output areas, are of a consistent size and are not subject to boundary changes between censuses. Where possible they are formed from groups of socially similar households and align with local features such as roads and railway lines. The comparability and stability of the geography is a key benefit to users of statistics which cannot be provided by other small area administrative geographies such as wards or parishes.

Following the 2011 Census, some boundary changes to SOAs were required and the new set of SOA boundaries was published in October 2012, although the stability of the geography has been largely maintained.

Three hierarchical levels of SOAs are available in Wales. LSOAs were designed to have a population of between 1,000 and 3,000 in 2011, and there are 1,909 of them in Wales. MSOAs were designed as aggregations of LSOAs, have a population of between 5,000 and 15,000 in 2011, and there are 410 of them in Wales. USOAs are aggregations of MSOAs and were defined in conjunction with local authorities in Wales. There 94 of them in Wales and they are only defined in Wales.

Further information on SOAs, can be obtained from the geography section of the ONS website (see weblinks).

Data collection and calculation

Frequency of publication

Data reference periods
Data are produced and reported annually and relate to the 30 June of each year.

Users, uses and context
Population estimates for LSOAs, MSOAs and USOAs are often used for research and analysis as, unlike other small area geographies such as wards, they are specifically designed for statistical purposes. In particular, they are used by both central government departments and local authorities for a range of purposes including planning and monitoring of services and as denominators for the calculation of various rates and indicators.

Rounding applied
Data are provided on an unrounded basis although the Office for National Statistics advises that any results presented from these data are rounded to the nearest 100 where practical.

Revisions information
The small area data (at super output area level) presented here have been revised so that they are consistent with the population estimates produced at national and local authority level for the same period. They also reflect changes made to population estimates from 2001 to 2010 in re-basing the data to be consistent with the results of the 2011 Census (see weblinks).
The ONS published revised mid-2012 to mid-2016 estimates of the population on 22 March 2018 due to methodological improvements. Therefore the figures for mid-2012 to mid-2016 within the statswales cube have been revised.
