Originally coined in 2001 in a report on racial tensions in the United Kingdom, the concept of “parallel lives” has become familiar in the European discourse on immigrant integration. There, it refers to what is perceived as the segregation of immigrant populations from the rest of society. However, the historical roots of this presumed segregation are rarely the focus of discussion. Combining quantitative analysis, archival research, and over one hundred oral history interviews, Parallel Lives Revisited explores the lives of immigrants from six Mediterranean countries in a postwar Belgian city to provide a fascinating account of how their experiences of integration have changed at work and in their neighborhoods across two decades.
