Texas demographer: "It's basically over for Anglos [in Texas]"

[ag]

I am afraid these sort of studies do not take into account assimilation. There is a lot of intermarriage. A lot of the third-generation "Hispanics" are barely Hispanic at all - and even that only for all sort of minority-preference purposes.  Still more don't even identify themselves as Hispanic.

Ignoring this also has the effect of exaggerating the poverty, lack of education, fertility, etc., etc. of the Hispanic population. It is the poorest and least educated that continue on unassimilated and easily identifiable as Hispanic. To a degree, we are confusing the causality: a lot of these people aren't poor and uneducated because they are Hispanic, but they are "Hispanic" because they are poor and uneducated. Of course, this is only part of the story: you don't have to be poor to self-identify as Hispanic. But assimilation is much easier for those higher up on the social scale.
