Amsterdam’s immigrants of Caribbean and southern Mediterranean origin have been characterized as modestly segregated from Dutch residents, and their residential assimilation has been expected to proceed rapidly. This article tests the hypothesis of spatial assimilation using both aggregate data on levels of segregation and individual-level analyses of the people who live in ethnic minority neighborhoods. Evidence is presented of assimilation for immigrants from the former colonies of Surinam and the Antilles, but Turks and Moroccans are shown to face stronger barriers. The former groups’ higher standing favors their mobility from ethnically distinct neighborhoods. There is a generational shift for Surinamese and Antilleans, while the Turks and Moroccans born in Amsterdam are as likely as the immigrant generation to settle in ethnic minority neighborhoods.
