In mid-2012 there were 34,753 lower layer SOAs (LSOAs) in England and Wales with a mean population of 1,630 and 7,201 middle layer SOAs (MSOAs) with a mean population of 7,860.
The LSOAs with the highest population densities are all in Inner London, with the most densely populated area in mid-2012 being Kensington and Chelsea 021C, where approximately 1,200 people were living in an area of 0.02 square kilometres.
In mid-2012 the least densely populated LSOA in England and Wales was Northumberland 019C in Northumberland National Park at 2.6 persons per square kilometre.
Super Output Area (SOA) population estimates are particularly important for use in many areas of research as they provide key demographic information on small geographic areas that were designed specifically for the purpose of enabling statistical analysis.
This product is part of the set of Small Area Population Estimates (SAPE). It includes estimates of the usually resident population as at 30 June of the reference year for Lower Layer and Middle Layer Super Output Areas (SOAs) in England and Wales by age and sex. These estimates are consistent with the local authority, regional and national population estimates. Estimates reflect the new SOA boundaries introduced for the publication of 2011 Census results.
This release also includes an additional table of supporting information:
Population Density for LSOA and MSOA.
These National Statistics are produced to high professional standards and released according to the arrangements approved by the UK Statistics Authority.
