Marriage‐Market Constraints and Mate‐Selection Behavior: Racial,Ethnic, and Gender Differences in Intermarriage

Despite theoretical consensus that marriage markets constrain mate‐selection behavior, few studies directly evaluate how local marriage‐market conditions influence intermarriage patterns. Using data from the American Community Survey, the authors examine what aspects of marriage markets influence mate selection, assess whether the associations between marriage‐market conditions and intermarriage are uniform by gender and across pan‐ethnic groups, and investigate the extent to which marriage‐market conditions account for group differences in intermarriage patterns. Relative group size is the most salient and consistent determinant of intermarriage patterns across pan‐ethnic groups and by gender. Marriage‐market constraints typically explain a larger share of pan‐ethnic differences in intermarriage rates than individual traits, suggesting that scarcity of co‐ethnic partners is a key reason behind decisions to intermarry. When faced with market constraints, men are more willing or more successful than women in crossing racial and ethnic boundaries in marriage.
