This report investigates the state of race relations in Britain during the late 1960s to determine the social and economic integration of immigrant populations. E.J.B. Rose, leading a team under the auspices of the Institute of Race Relations, synthesized extensive survey data and sociological research to evaluate the impact of post-war migration on British society. The work argues that systemic challenges in housing, employment, and education created significant barriers to integration, necessitating a structured policy response to prevent long-term social fragmentation.

Researchers and historians recognize this report as a foundational document for understanding the development of British multicultural policy in the post-war era. Experts frequently note the immense scale of the data collection, which remains a primary reference point for longitudinal studies on British social integration.
