context: Minority ethnic groups include White people in Zimbabwe, who make up less than 1% of the total population. White Zimbabweans are mostly of British origin, but there are also Afrikaner, Greeks in Zimbabwe, Portuguese people, Franco-Mauritian and Dutch people communities. The white population dropped from a peak of around 278,000 or 4.3% of the population in 1975 to possibly 120,000 in 1999, and was estimated to be no more than 50,000 in 2002, and possibly much less. The 2012 census lists the total white population at 28,782 (roughly 0.22% of the population), one-tenth of its 1975 estimated size. Most emigration has been to the United Kingdom (between Zimbabweans in the United Kingdom Britons are of Rhodesian or Zimbabwean origin), South Africa, Botswana, Zambia, Canada, Australia and New Zealand. Coloureds form 0.5% of the population, and various Asian people ethnic groups, mostly of Indian and Chinese origin, are also 0.5%.
