Intermarriage and Homogamy: Causes, Patterns, Trends

TLDR

Sociologists have largely studied endogamy and homogamy in terms of race/ethnicity, religion, and socioeconomic status, and this paper reviews empirical research on these patterns. The study aims to answer four questions: the extent of group endogamy, its temporal changes, related factors, and the convergence of partner choice dimensions. The authors evaluate past research by discussing its strengths and weaknesses.

Abstract

"Although many characteristics play a role in the choice of a spouse, sociologists have most often examined endogamy and homogamy with respect to race/ethnicity, religion, and socioeconomic status.... I summarize empirical research by answering four questions: (a) To what extent are groups endogamous and how do groups differ in this respect? (b) How has endogamy changed over time? (c) Which factors are related to endogamy? (d) How do various dimensions of partner choice coincide? [I then] discuss strengths and weaknesses of past research."
