The Super Output Area (SOA) estimates for England and Wales for mid-2002 to mid-2010 have been revised following the 2011 Census. The revised series allows an understanding of how populations in England and Wales have changed across the decade in small areas, illustrated in the case study for Birmingham.
The size of the revision is dependent on the size of the difference between the official (census based) mid-2011 estimate for each lower layer SOA (LSOA) and what the mid-2011 LSOA estimates would have been had the 2011 Census results not been available.
More than 60% of LSOAs and more than 75% of middle layer SOAs (MSOAs) were revised by less than ±5% across the decade.
The largest LSOA revisions were mostly in university areas, with the largest revision in Leeds 055H where the population was overestimated by approximately 2,800 people.
Some of the largest MSOA revisions were in Newham local authority which saw an overall upward revision of 68,000 people across the decade.
This product includes population estimates for lower and middle layer Super Output Areas (SOAs) in England and Wales by age and sex, revised in line with the results of the 2011 Census.
Population estimates for Mid-2001, re-based on 2011 lower and middle layer Super Output Areas (SOAs) Census boundaries are also included.
