Migration statistics can be used to estimate the flow of migrants in and out of the UK and to estimate the number of migrants living in the UK (the stock). One estimate of the stock is the number of people living in the UK who were born in another country.
The Office for National Statistics produces the Annual Population Survey, a survey of households in the UK. It includes a question on respondents’ country of birth
The Annual Population Survey has been produced since 2004. Below you can select a maximum of three countries or world regions to create your own graph that shows how that population has changed in the UK since 2004.
The foreign born population is affected by both international migration and deaths of existing migrants.
The ONS have produced a user guide that covers frequently asked questions relating to the Annual Population Survey (see here)
