Racial Pairings and Fertility: Do Interracial Couples Have Fewer Children?

Our overall goal is largely descriptive-to compare recent fertility patterns between racially endogamous and exogamous couples in the United States. Evidence of lower fertility among exogamous or interracial couples arguably provides indirect evidence of social distance and cultural and economic integration.

The growth of interracial marriage and cohabitation has fueled the rise in biracial or mixed-race children. Fertility rates are uneven among racial and ethnic groups, seemingly rooted in stigma and cultural differences (e.g., fertility norms). Whether fertility is different among interracial couples is unclear: Fertility rates that largely conform to the population of racially endogamous White couples provide evidence of social integration whereas differential fertility may reveal gender dynamics in fertility decision-making, including power relationships that depend on the race of male and female partners.

We pool data from the 2008 to 2017 American Community Survey to compare past-year fertility patterns among endogamously and interracially married and cohabiting couples.

Fertility is generally lower among racially exogamous than endogamous unions, especially among Asian American-White couples. Fertility among American Indian-White couples is much closer to patterns of White couples than of American Indian couples. Fertility among other interracial couples nevertheless varies by the race of male partners. That is, fertility of the Black male/White female and the Hispanic male/White female couples is similar to patterns found among endogamous Black and Hispanic couples, respectively. The White male/Black female and the White male/Hispanic female couples follow the fertility patterns of White couples.

In general, the fertility levels of interracial couples are intermediate between those of endogamous White couples and their endogamous Black, Hispanic, or American Indian counterparts, but vary significantly by the race-gender mix of partners.
