The Sri Lanka-born presence in Britain is down to both historic links and asylum movements caused by its long and bitter civil war.
The overwhelming majority live in London � about 50,000 in 2001 � although there have been proportionately significant arrivals to communities in the East and West Midlands.
About a tenth of British areas have no Sri Lankan-born people in their neighbourhoods, but London has seen some interesting changes in the past 10 years.
It appears from the data that Sri Lanka-born families are moving from inner London areas to outer London, a trend seen in the history of many immigrant communities.
