Q. Hispanics are an ethnicity, not a race, so how can we know that the next generation of Mexican immigrants won’t be very different?
A. I could imagine one event that would drive up new Hispanic immigrants’ children’s test scores substantially: another Revolution in Mexico. If rich white Mexicans, like the world’s richest man Carlos Slim, had to flee for their lives, the next generation of Mexican newcomers might be a lot like the prosperous Cubans who arrived in Miami after Fidel.
But the way immigration from Mexico has been working since the end of the last Revolution almost a century ago is via family chain migration. New immigrants tend to belong to the extended families of old immigrants.
