Matthijs Kalmijn examines the causes, patterns, and trends of intermarriage and homogamy, focusing on race/ethnicity, religion, and socioeconomic status. He outlines three main factors influencing marriage choices: individual preferences for certain characteristics in a spouse, the influence of third parties in the selection process, and constraints of the marriage market. Empirical research shows that groups vary in their endogamy, with some groups more endogamous than others. Over time, endogamy has changed, with some groups becoming more open. Factors related to endogamy include socioeconomic status, religion, and geographic location. Intermarriage can have cultural and socioeconomic implications, but marriage patterns do not always reflect social differentiation. Marriage patterns are influenced by both preference and opportunity, and demographic trends such as declining marriage rates and rising divorce rates complicate their interpretation. Theoretical work on intermarriage and homogamy suggests that individuals choose spouses based on socioeconomic and cultural resources, and that group identification and third-party sanctions also play a role. Marriage markets are influenced by structural arrangements, such as residential segregation and local settings like schools and workplaces. Empirical studies show that intermarriage rates vary by race/ethnicity, religion, and socioeconomic status, with some groups more endogamous than others. Trends in intermarriage and homogamy show an increase in intermarriage among new ethnic groups and a decline in ethnic endogamy, interpreted through assimilation theories. Religious homogamy has also changed, with some groups becoming more endogamous over time. Socioeconomic homogamy has declined in many industrialized countries, with education and class background playing a role. Overall, intermarriage and homogamy are influenced by a complex interplay of individual preferences, group dynamics, and structural factors.Matthijs Kalmijn examines the causes, patterns, and trends of intermarriage and homogamy, focusing on race/ethnicity, religion, and socioeconomic status.
