African migration to Britain

The foreign-born population of the United Kingdom includes immigrants from a wide range of countries who are resident in the United Kingdom. In the period January 2010 to December 2010, there were 19 foreign-born groups that consisted of at least 100,000 individuals residing in the UK (people originating from Australia, Bangladesh, China, France, Germany, India, Italy, Jamaica, Kenya, Nigeria, Pakistan, Philippines, Poland, Republic of Ireland, Somalia, South Africa, Sri Lanka, United States and Zimbabwe).

At the time of the UK census conducted in April 2001, 8.3 percent of the country's population were foreign-born. This was substantially less than that of major immigration countries such as Australia (23 percent), Canada (19.3 percent) and the USA (12.3 percent). In 2005, the foreign-born population was estimated at 9.1 percent, compared to a European Union average of 8.6 percent. The 2011 census recorded 7,337,139 foreign-born residents in England, corresponding to 13.8 percent of the population. The foreign-born population of Wales was recorded as 167,871 (5.5 percent),Scotland's as 369,284 (7 percent) and Northern Ireland's as 119,186 (6.6 percent), making the total foreign-born population of the UK 7,993,480.
