Black British is a term used to describe British people of black African descent, especially those of Afro-Caribbean background. The term has been used from the 1950s to refer to Black people from former British colonies in the West Indies (i.e. the New Commonwealth) and Africa, who are residents of the United Kingdom and consider themselves British. Others are also from former French-speaking colonies in Africa such as Senegal and the Democratic Republic of the Congo (which was Belgian), and many of the Black Africans in Britain still speak French as well as their own native languages.
The term 'black' has historically had a number of applications as a racial and political label, and may be used in a wider socio-political context, to encompass a broader range of non-European ethnic minority populations in Britain, though this is a controversial and non-standard definition.
Black British is primarily used as an official category in UK national statistics ethnicity classifications, where it is sub-divided into 'Caribbean', 'African' and 'Other Black' groups.
