We are all Germans now: Many of my posts deal with American ethnic groups, but I always treat people as though they belong to one group. The General Social Survey recorded if respondents mentioned belonging to a second ethnic group. Here are their answers--the first is the main identity, the second is the most common second identity given, along with the percentage saying so:
Percent saying that the second group is their secondary ethnicity
Black--American Indian 25.8%
Mexican--American Indian 5.7
French Canadian--Irish 22.6
Greek--German and Italian 19.1
American Indian--Black 14.3
The first thing that jumps out at me is how common German is as a secondary identity! Of course, this is a large American group, but I can't help thinking that perhaps Germans have been very open to intermarrying, or that of the many ancestries that mutt Americans have, German is one that is remembered for some reason. It is also interesting that poor minority groups only have some other poor minority group as their secondary ethnicity.
