Controversy exploded in 2005 over a paper at the Annual Conference of the Royal Geographical Society and the Institute of British Geographers which claimed that ethnic segregation in Britain was increasing, ghettos had formed and some British cities were more segregated than Chicago. The paper asserted that indexes failed to measure segregation and should be abandoned in favour of a threshold schema of concentrations using raw data. These assertions were repeated by Trevor Phillips, Director the Commission for Racial Equality, in an inflammatory speech claiming that Britain was sleepwalking into American-style segregation. The argument of this paper is that the index approach is indeed necessary, that ethnic segregation in Britain is decreasing, that the threshold criteria for the claim that British ghettos exist has manufactured ghettos rather than discovered them. A Pakistani ghetto under the schema could be 40 per cent Pakistani, 30 per cent White, 20 per cent Indian and 10 per cent Caribbean. In 2000, 60 per cent of Chicago's Blacks lived in a true ghetto of tracts that were 90-100 per cent Black. Adapted from the source document.
In the past two decades, migration scholars have revised and revitalized assimilation theory to study the large and growing numbers of migrants from Latin America, Asia, and the Caribbean and their offspring in the United States. Neoclassical and segmented assimilation theories seek to make sense of the current wave of migration that differs in important ways from the last great wave at the turn of the 20th century and to overcome the conceptual shortcomings of earlier theories of assimilation that it inspired. This article examines some of the central assumptions and arguments of the new theories.
