Since Sweden joined the European Union in 1995 (at the same time as some of its Nordic neighbours and Austria), its citizens have been able to freely seek work in Britain under free market rules.
Perhaps not surprisingly, the numbers arriving from Sweden doubled in the 10 years to 2001.
Some 22,000 Sweden-born people comprise one of the smallest EU groups in the UK, with the vast majority found in London or the South East.
Areas registering clusters in London indicated that most were in well-paid business or professional posts. Some other areas of the country did not register anyone born in Sweden at all.
