The annual population by country of birth and nationality publication provides population estimates by country of birth and nationality and looks at how these figures have changed over time.
The estimates are produced using the Annual Population Survey (APS), which (other than the Census and Census Coverage Survey), is the largest household survey in the UK. The APS is constructed from the Labour Force Survey (LFS) plus various local boosts that increase the size of the sample. The main purpose of the LFS is to provide information on the UK labour market, however it also includes data on a number of other variables, such as country of birth and nationality.
The population by country of birth and nationality tables are used by central and local government for planning and monitoring service delivery, resource allocation and managing the economy.
