Anti-miscegenation laws have played a large role in defining racial identity and enforcing the racial hierarchy.
The United States has many ethnic and racial groups, and interracial marriage is fairly common among most of them.
Some racial groups are more likely to intermarry than others.
Of the 3.6 million adults who got married in 2013, 58% of Native Americans, 28% of Asians, 19% of blacks and 7% of whites have a spouse whose race was different from their own.
For example, in 1880, the tenth US Census of Louisiana alone counted 57% of interracial marriages between these Chinese to be with black and 43% to be with white women.
It was discovered by historian Henry Louis Gates, Jr in the African American Lives documentary miniseries that NASA astronaut Mae Jemison has a significant (above 10%) genetic East Asian admixture.
More than six-in-ten say it would be fine with them if a family member told them they were going to marry someone from any of three major race/ethnic groups other than their own.
Interracial marriages increased from 2% of married couples in 1970 to 7% in 2005 According to a Pew Research Center analysis of census data conducted in 2013, 12% of newlyweds married someone of a different race.
(This share does not take into account the “interethnic” marriages between Hispanics and non-Hispanics).
Gates speculated that the intermarriage/relations between migrant Chinese workers during the 19th century and black, or African-American slaves or ex-slaves may have contributed to her ethnic genetic make-up.
In the mid 1850s, 70 to 150 Chinese were living in New York City and 11 of them married Irish women.
In Cameron County, 38% of black people were interracially married (7/18 families) while in Hidalgo County the number was 72% (18/25 families).
