BBC News: Brits Abroad. This is a clickable map of the world with stats about emigration to each area.
An estimated 5.5m British people live permanently abroad – almost one in 10 of the UK population. The emigration of British people has happened in cycles over 200 years. The trend is now rising again: some 2,000 British citizens moved permanently away from the UK every week in 2005. This unique project aims to explain where people have gone. On the regional and country pages you will find data on what we know about that part of the world.
This data follows on from the BBC News article, 5.5m Britons ‘opt to live abroad’. I wouldn’t have expected Australia and Spain to be the top destinations, or that Canada and the US are about equal. Both are an interesting read.
