Mental arithmetic and juggling with figures statistics in French and British policy towards colonial immigration in the 1950s

In the 1950s, Britain and France faced a comparable development of increasing immigration from current or former colonial territories, which was perceived as problematic. Immigration statistics had a central role in governmental or administrative discussions; however, both for general difficulties inherent in immigration statistics and for specific problems due to ‘post‐colonial’ nationality arrangements, these statistics are of limited reliability. The ways statistics were used differed as reactions to ‘colonial’ immigration in Britain and France differed, corresponding to their respective post‐war experiences and political aims. The official use of statistics against this background serves to reveal certain national characteristics in their reaction to ‘colonial’ immigration.
