Ethnicity – a context
Over a period of two decades after the Second World War, people from Pakistan, India, Bangladesh and the Caribbean migrated to Britain in large numbers as a result of post-war labour shortages.
Later, during the 1970s, people of South Asian origin came from Africa in response to the Ugandan and Kenyan governments’ Africanization policies. Since then, the legal entry of unskilled, non-white people has been limited to the dependents or spouses of these earlier immigrants.
There has also been significant immigration of Black Africans since the 1980s. According to the 2001 census, the UK has a non-white minority ethnic population of 4.6 million, representing 7.9% of the total population.
Those categorized as “Asian or Asian British” (Indian, Pakistani, Bangladeshi and other Asian) numbered 2.3 million, comprising 4% of the UK population, whilst those termed “Black or Black British” (including Black Caribbean, Black African and Black Other) comprised 1.1 million.
