The Flynn Effect among Mexican Americans: Using General Social Survey data, I calculated the mean IQs for each of the past four decades for people of Mexican ancestry who were born in the United States. Here are the numbers:
The 1990s saw more than a 7 point increase over the previous decade, and the gains continued into the 21st century. Let's compare them to white Americans:
I'm not sure why increases are seen for the groups--the white gain might be explained, in part, by increases in mean age (vocabularies expand a bit with age)--but higher IQs indicate that people will thrive, so this is a good sign for Mexican Americans. (Keep in mind that the analysis concerns people born here, so immigrants, legal and illegal, are excluded.)
