Religiosity and assimilation: Razib, over that Gene Expression II, shows that Muslims are better integrated in America than England or France because there is a better fit here in terms of religiosity. Muslims tend to be religious, and so do other Americans.
I wanted to see if there was a general pattern of religiosity and assimilation. The General Social Survey asked 202 immigrants how often they attend religious services, and how proud they are of America's history. It's high time I used the proper statistic, so I calculated gamma, which turned out to be .16. So there is a positive association, albeit a small one. On average, religious immigrants have a better attitude about America.
I think I just found an area where Mexican immmigrants look good, or at least seem like a good match with American culture. They are more religious than immigrants in general, more religious than American-born people of Mexican ancestry, and they attend church more often than native-born Americans in general. They are as likely as other immigrants to be proud of America's history, and Mex-Ams born in this country are more likely than the typical American to be proud of the country's past. (Results are not shown 'cuz I got no damn time!)
