This article is concerned with contrasts in the geographical distribution of people from the white and ethnic minority groups within Great Britain. It begins by describing regional variations in ethnic composition and maps the distribution of ethnic minority groups at the local authority district scale. The article then demonstrates that most people from the white ethnic group live in wards with very small populations from ethnic minority groups, while people from ethnic minority groups tend to be found where the share of minorities in the resident population is relatively high. The focus then switches to the neighbourhood (enumeration district) scale, at which a very marked degree of spatial segregation in the distribution of ethnic groups is revealed. The local authority districts in which the degree of segregation of people from ethnic minority groups relative to the rest of the population is greatest are listed.
