United Kingdom demographics
‘Britain’s native population is remarkably stable. Since the early 1990s births have tallied so closely with deaths and emigration that the head count has been flat, at 52m. Almost all of the country’s population growth is down to immigration. The number of non-natives living in Britain rose from 4.8m in 1995 to 13.4m in 2011. Immigrants might make up a quarter of the country’s population by 2015,’ (The Economist 02 Nov 2013).
