This paper presents a study of the relationship between assortative mating and ethnic segregation in Stockholm, Sweden. We examine how segregation influences couple formation, where newly cohabiting couples choose to live, and how union formation and mobility jointly influence residential segregation. 1990-2012 Swedish population registers allow us to identify the onset of cohabiting relationships and residential mobility for newly cohabiting couples. Estimates based on two-sex models of assortative mating and discrete choice models of residential mobility reveal that non-Western ethnic groups are largely confined to non-Western partners and to neighborhoods with disproportionately high representations of non-Western groups. Simulations based on our empirical models indicate that assortative mating and residential mobility both contribute to segregation. Tendencies to partner with singles who live nearby and who share the same ethnicity and nativity increase segregation. The results demonstrate how residential segregation and homogamous patterns of union formation are mutually constitutive and suggest that more attention should be paid to family demography when studying segregation.

本文介绍了瑞典斯德哥尔摩的同类交配与种族隔离之间关系的研究。我们研究了隔离如何影响夫妻的形成，新同居的夫妻选择居住的地方，以及工会的形成和流动性如何共同影响居住隔离。1990-2012 年的瑞典人口登记使我们能够确定新同居夫妇的同居关系和居住流动的开始。基于选型交配的双性模型和住宅流动的离散选择模型的估计表明，非西方种族群体主要局限于非西方伙伴和非西方群体代表比例过高的社区。基于我们的经验模型的模拟表明，同类交配和居住流动性都有助于隔离。与居住在附近并且具有相同种族和出生地的单身人士合作的倾向加剧了隔离。结果表明居住隔离和同性结合模式如何相互构成，并表明在研究隔离时应更多地关注家庭人口统计学。
