This paper assesses the residential segregation of German immigrants from Turkey, Italy, the Balkans and eastern Europe with a special focus on the link between social and ethnic segregation. Microdata from the German Socioeconomic Panel Study (SOEP) are used. A new dataset provided by the microm Micromarketing-Systeme und Consult GmbH makes accessible information on participants’ immediate residential environments at the micro-neighbourhood level where an average neighbourhood contains only eight households. Substantial levels of residential isolation in the form of own-group overexposure are found for all four migrant groups. Based on previous research, an enhanced methodology is proposed to measure the effect of socioeconomic neighbourhood sorting on ethnic residential segregation. It is shown that differences in income, education, language skills and village/city size have the potential to account for 29–84 per cent of the residential isolation of the four migrant groups.
