While the numerical growth of the immigrant population in France has been documented since the early 1990s, few studies have looked at changes in the spatial distribution of this population. Most research has emphasised immigrants' concentration in large cities and their suburbs. The present study aims to show how the spatial differentiated distribution of immigrants has changed at the national level over the past four decades in mainland France and Corsica, with analyses centred on non-metropolitan areas. Drawing on census data at the national level between 1975 and 2015, we show that while the immigrant population has increased, it has also spread increasingly into non-metropolitan areas. This deconcentration of the immigrant population has been accompanied by a diversification of geographical origins at the local level, suggesting joint or even linked migratory dynamics in non-metropolitan areas.

法国移民向非大都市地区的空间分散（1975-2015）

虽然自 1990 年代初以来已记录了法国移民人口的数量增长，但很少有研究关注这一人口空间分布的变化。大多数研究都强调移民集中在大城市及其郊区。本研究旨在展示过去 40 年法国大陆和科西嘉岛在国家层面上移民的空间差异分布如何变化，分析以非大都市地区为中心。根据 1975 年至 2015 年间国家层面的人口普查数据，我们表明，虽然移民人口有所增加，但也越来越多地蔓延到非大都市地区。移民人口的分散伴随着地方一级地理起源的多样化，
