The Fourth National Survey of Ethnic Minorities comprises a definitive study of ethnic minority experience in Britain and the ways in which it is changing. The main report has been widely referenced (Modood et al., 1997 'Ethnic Minorities in Britain: Diversity and Disadvantage' Policy Studies Institute, London), and the data are stored in the ESCR data archive:
