The Office for National Statistics (ONS) has released revised mid-2002 to mid-2008 population estimates for local authorities in England and Wales. The revisions have been produced as a result of improvements to ONS methodology, introduced as part of the cross-government Migration Statistics Improvement Programme.
The new population estimates use an enhanced method for apportioning migrants to local authorities incorporating modelling using up-to-date survey and administrative data. Higher Education Statistics Agency data is utilised to improve estimates of student internal migration.
ONS have produced a population estimates analysis tool to help users understand the main patterns and trends in the population estimates. Users can select specific areas of interest and compare local estimates across time and with estimates at higher levels of geography.
Data users are also able to select specific age groups and view the components of population change for the chosen area.
Mid-2009 population estimates will be published on 24th June 2010, and will be based upon the new methodology.
