Unlike their nearest geographical neighbours in Europe, Spain-born people are more widely spread in Britain than those born in Portugal.
Of the 54,000 living in Britain at the time of the 2001 Census, about four in every 10 were in the capital and just under a fifth of those remaining spread through the South East.
The university towns of Edinburgh, Manchester, Oxford, Cambridge and Bristol also had clusters in similar sizes to other EU nationalities.
The modest increase of 15,500 Spain-born people in Britain over the 10 years to 2001 was more evenly split than for other countries: just a quarter of the increase was in London, although some areas saw falls.
