Out-marriage is least common among which ethnic/racial group in the US?

Out-marriage, or the practice of marrying outside one's ethnic or racial group, is least common among Whites/Caucasians in the U.S. This phenomenon can be attributed to a variety of social and cultural factors. Individuals within the White/Caucasian demographic often have a greater historical tendency to marry within their own group, influenced by factors such as social norms, cultural identity, and family expectations.

Cultural cohesion within the community can also play a critical role, as shared cultural practices and values are significant considerations when forming marital relationships. Additionally, while other groups, such as Black/African Americans, Hispanics/Latinos, and Asians, have varying rates of out-marriage that may reflect broader social integration and changing demographics, Caucasians generally maintain a higher incidence of intra-group marriages.

In summary, the nature of cultural identity, community expectations, and varying social integration levels contributes to the lower rate of out-marriage among Whites/Caucasians compared to other ethnic or racial groups in the United States.
