Intergroup marriage: an examination of opportunity structures.

Though a number of authors have noted the increase in interracial marriages in the United States over the past few decades, few researchers have systematically examined variables that affect the opportunity for intergroup marriage among several different groups: Whites, African Americans, Asians, and Hispanics. In this paper we examine several “opportunity” variables and their relationship to intergroup marriage for couples age 40 or younger: immigration, military service, metropolitan residency, age, region, college attendance, and socioeconomic status. We examine these relationships for African, White, Asian, and Hispanic Americans. Results for both males and females are presented. The analysis is based on data from the 1990 census. The propensity to marry within one's own group dropped slightly for all groups but Asian Americans from 1980 to 1990. White and Black Americans continue to have the highest endogamy rates. Hispanic and Asian Americans have lower rates, and regional variations are highest for them as well. The results suggest that the opportunity variables are important factors affecting rates of intergroup marriage.
