The subnational population estimates for England and Wales for mid-2002 to mid-2010 have been revised following the 2011 Census. The revised series provides a consistent time-series of population estimates to mid-2011 for each local authority (LA) in England and Wales.
The size of the revisions is dependent on the size of the difference between the official (Census-based) mid-2011 estimates for each LA, and what the mid-2011 estimates would have been had 2011 Census results not been available.
More than 70% of LAs were revised by fewer than 5,000 people across the decade, although some LAs had larger revisions. In 88% of LAs the total population was revised by less than 5% across the decade.
Most of the largest revisions were for LAs in London. The largest revision was for Newham, with an upward revision of 68,000 people across the decade. The largest percentage revision was for the City of London, with a downward revision of 38% across the decade.
Estimates of the usually resident population as at 30 June of the reference year, revised in line with the 2011 Census. The release includes a report on changes made to the population estimates to take account of the Census results and how these changes have been allocated over the decade. Estimates reflect the administrative boundaries in place on 30 June 2011.
The mid-2001 to mid-2011 tables have been reformatted since their release, more details can be found within the data files.
