Population by Country of Birth
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 flow of migrants is the United Nations definition of a migrant; someone who moves to another country for at least 12 months.
The Office for National Statistics produce estimates of international migration based on the International Passenger Survey, a survey of passengers arriving and departing the UK. Someone arriving to the UK intending to stay for 12 months or more is an immigrant and someone departing the UK for 12 months or more is an emigrant. The migration figures are also adjusted to include asylum seekers. Net migration is the number of immigrants minus the number of emigrants.
The headline net migration figure for the UK is updated quarterly. The latest estimate released is that total net migration to the UK in the year ending March 2020 was 313,000.
The graph below shows how current levels of net migration compare to previous years levels.

5. The International Passenger Survey records the nationality of those interviewed so estimates of migration by citizenship can be produced. Table 1 below shows a breakdown of the latest figures.
More British citizens leave the country than arrive. EU net migration is currently 58,000 compared to 316,000 from outside the EU.
