Summary

These modelled annual population estimates were created for use the GLA's population projections. They are intended to provide a consistent series of annual population and components of change between census years with all change accounted for by the standard components of change (births, deaths, and migration). The official mid-year population estimates published by ONS are available here. The original detailed internal migration data published by ONS is available here. An overview of the general approach used to create these estimates is described in this presentation delivered at the 2022 BSPS conference. * 17 April 2023 code for producing the modelled 2021 detailed internal migration flows is now available on Github
