The U.S. Census Bureau has begun to release the statistics of Summary File 2, which includes 250 population groups: the Population, 132 race groups, 78 American Indian and Alaska Native tribe categories (reflecting 39 individual tribes), and 39 Hispanic or Latino groups.
As it relates to same-sex partners, SF 2 is of limited
value, since it only includes the race group of the main householder.
The race group or origin of the partner of the main householder is not
indicated. Hence, it is impossible to determine how many of these
couples are of the same race group or origin, or interracial.
Same-sex couples. Main householder who is Cambodian alone; by
