Other data indicating that Mex-Ams are ethnocentric and strongly tied to Mexico: In earlier posts, I presented evidence from the General Social Survey (GSS) that Mexican Americans are comparatively ethnocentric. Another way to look at it is to see how many of them see themselves as "American only"--people with no roots anywhere except for here. According to the GSS, Mexicans are 5.2% of the population but are only 2.3% of those saying they are only American. Blacks, for example, are much more likely to say yes to this question, even though they could easily identify with Africa if they chose to.
