Gender and ethnic differences in marital assimilation in the early twentieth century

Historical research on intermarriage has overlooked how distinctive patterns of ethnic settlement shape partner choice and assumed that the mate selection process operated the same way for men and women. This study utilizes a sample of young married adults drawn from the 1910 Census IPUMS to examine 1) whether ethnic variation in partner choice was shaped by differences in group concentration and distribution and 2) if factors shaping outmarriage were gendered. About one fifth of young married Americans had spouses of a different ethnic background in 1910, though there was considerable ethnic variation in outmarriage propensities. Barriers to intermarriage fell at different rates, depending upon ethnic group, sex, and region of settlement; they were weakest for first- and second-generation English men. Structural factors such as group size operated differently for men and women; while larger group representation increased men's odds of outmarriage to both native stock and other white ethnic wives, women from the ethnic groups with the largest presence were significantly more likely to wed fellow ethnics than the native stock. Ultimately, even if they resided in the same location, the marriage market operated in different ways for ethnic women and men in search of mates.
