We study the intersection of international migration and sexual preference from a socio-demographic perspective by looking at same-sex couples among migrants in Germany. Despite increasing ethnic diversity and greater social and legal liberality toward non-normative living arrangements, there are hardly any available quantitative data on this vulnerable group, which crosses two social boundaries. Drawing on the scientific-use file of the German Microcensus (2013), we estimate the prevalence of same-sex couples among female and male migrants, and describe their socio-demographic characteristics. We use different approaches to imputing data to account for the possibility that the reported information on same-sex relationships may be missing or wrong, and consider different definitions of “migrant status”. Our results show that the share of couples who were same-sex was smaller among the immigrant (0.2 to 1.4%) than among the native population (0.6 to 2.0%). Moreover, migrants in a same-sex couple were more similar in terms of other socio-demographic variables (age, education) to natives in a same-sex union than to migrants in an opposite-sex union. This study contributes to the LGBT social science literature by providing the first quantitative description of this minority-in-a minority group in Germany.
