The United Kingdom is an ethnically diverse society. The largest ethnic group in the United Kingdom is White British, followed by Asian British. Ethnicity in the United Kingdom is formally recorded at the national level through a census. The 2011 United Kingdom census recorded a reduced share of White British people in the United Kingdom from the previous 2001 United Kingdom census. Factors that are contributing to the growth of minority populations are varied in nature, including differing birth rates and Immigration.
White British is an ethnicity classification used for the white population identifying as English, Scottish, Welsh, Cornish, Northern Irish, or British in the United Kingdom Census. In the 2011 census, the White British population was 49,997,686, 81.5% of Great Britain's total population. For the United Kingdom entirely, due to different reporting measures within Northern Ireland which includes all those who identified as British with those who identified as Irish, an amalgamated total of 52,320,080 including those who identified as White Irish in Great Britain is given making up 82.8% of the population.

The Romani people have several distinct populations, the largest being the Roma and the Calé, who reached Anatolia and the Balkans in the early 12th century, from a migration out of the Indian subcontinent beginning about 1st century – 2nd century AD.
