Before the 2001 Census, people from the Baltic states of Lithuania, Latvia and Estonia were counted as part of the USSR. They are now counted as a separate group but no proper comparison with previous counts is possible.

About 10,000 people from the Baltic states were living in Britain in 2001, with the largest clusters in London, particularly East End areas like East and West Ham and Plaistow. The largest clusters outside the capital were in Bradford and Leicester.

All three countries include large ethnically Russian populations; some of the Baltic state-born people in Britain may actually describe themselves as Russian rather than Lithuanian, Lativan or Estonian.
