The article focuses on immigrants in Great Britain. According to Mohamed Osman, a Somali immigrant who runs a telephone centre in the heart of Toxteth, black Africans now outnumber West Indians and their British-born descendants--a group that he refers to as "blacks". For much of the 20th century, immigrants into Britain followed, in reverse, the paths trodden by imperial administrators. Ex-colonies in Ireland, the West Indies and the Indian subcontinent supplied the largest groups of settlers. But history and proximity matter less these days. Since 1999, countries outside the Commonwealth and the European Union have been larger net exporters of people to Britain than the other two sources combined. The 1991 census recorded fewer than half as many black Africans as Afro-Caribbeans in Britain. In 2001, the numbers were 485,000 and 566,000. Since then, the balance has tipped. Four out of the past five quarterly Labour Force Surveys estimate the black African population as equal to or greater than the Afro-Caribbean population, and the most recent survey puts them well ahead at 618,000. The oldest ethnic minority group to arrive in Britain in any numbers has been overtaken by the newest. Immigration and asylum are part of the reason. Oddly, the sea change in Britain's ethnic minority population has gone virtually unnoticed by politicians and pressure groups. One way that ethnic groups force governments to engage with them, of course, is to be hopeless. That is not the case for black Africans--or, at least, not universally. Single-parent households are considerably rarer than among Afro-Caribbeans. Anglophone immigrants from countries like Nigeria and Ghana are aspirational; thanks mostly to them, 38% of black African adults hold higher educational qualifications--more than any other ethnic group. But younger arrivals from war-torn nations are not faring so well.
