British migration to Spain has resulted in Spain being home to one of the largest British-born populations outside of the United Kingdom. Migration from the UK to Spain has increased rapidly since the late 1990s and the British population of Spain in 2006 was estimated to be about 761,000 (more than twenty-five times the population of Gibraltar). Of these, according to the BBC and contrary to popular belief, only about 21.5% are over the age of 65.
In 2007 the officially registered British-born population of Spain numbered 315,000 (though various estimates place the true figure significantly higher, ranging from 700,000 to more than 1,000,000), constituting 8.09% of the foreign population and making Britain the fourth most common country from which immigrants to Spain originate (behind Morocco, Romania, and Ecuador).
According to the data collected by the INE, the distribution of Britons in Spain is as follows
Academic research has shown that a section of the British population in Spain is poorly integrated into Spanish society. A survey of 340 British migrants in the Province of Málaga, for example, found that one third rarely or never met Spanish people, apart from in shops and restaurants, and that 60 per cent did not speak Spanish well. Moves are afoot to improve integration.
