Selection, alignment, and their interplay: Origins of lifestyle homogamy in couple relationships

Abstract

The present study examines different processes leading to lifestyle homogamy in married and cohabiting couples using data from the German Socioeconomic Panel (n = 3,490 couples). The analyses first suggest that alignment over time promotes homogamy of leisure-related lifestyles, especially with respect to action-oriented activities. However, intermediate stages in the life course (i.e., phases of active parenting and labor force participation) tend to inhibit alignment, whereas cues indicating a high-quality match (e.g., educational homogamy and being in a long-term or a marital relationship) promote alignment. Second, we find evidence for selection effects in that not only homogamy but also convergence of lifestyles over time may increase couples' resilience to relationship breakup.
