MUCH of today's debate about immigration revolves around the same old questions: How much do immigrants contribute to production? Do they take jobs away from people born in the United States? And what kinds of social services do they use? Yet every immigrant represents much more than just one worker or one potential citizen. To understand fully how immigration will shape the economy, you can't just look at one generation — you have to look into the future.

Sociologists and economists are just beginning to study the performance of second- and third-generation members of immigrant families. Because of the variety of experiences of people from different countries and cultures, it's not easy to generalize. But recent research has already uncovered some pertinent facts.

Education is a good place to start, because it's strongly correlated with future earnings. Children of immigrants complete more years of education than their native-born counterparts of similar socioeconomic backgrounds. "You can expect a child of immigrants whose parents have 10 years of education to do a lot better than a child of natives whose parents have 10 years of education," said David Card, a professor of economics at the University of California, Berkeley. Being a child of immigrants, he said, "sort of boosts your drive."
