The Zimbabwean population in Britain has been changing rapidly for two reasons, both of which mean that the 2001 figures are almost certainly substantially out of date.
Firstly, the expansion in NHS staff has attracted many more Zimbabwean doctors and nurses than in previous decades.
Secondly, the political turmoil in the country led to a sharp rise in asylum seekers fleeing the regime of President Robert Mugabe.
Zimbabweans are overwhelmingly concentrated in London and its northern commuter towns. Luton, Milton Keynes and Slough are some of the key areas to have experienced rises in southern African populations over the past decade.
