The extraordinary Mexican migration that delivered millions of illegal immigrants to the United States over the past 30 years has sputtered to a trickle, and research points to a surprising cause: unheralded changes in Mexico that have made staying home more attractive.
A growing body of evidence suggests that a mix of developments–expanding economic and educational opportunities, rising border crime and shrinking families–are suppressing illegal traffic as much as economic slowdowns or immigrant crackdowns in the United States.
Douglas S. Massey, co-director of the Mexican Migration Project at Princeton, an extensive, long-term survey in Mexican emigration hubs, said his research showed that interest in heading to the United States for the first time had fallen to its lowest level since at least the 1950s. “No one wants to hear it, but the flow has already stopped,” Mr. Massey said, referring to illegal traffic. “For the first time in 60 years, the net traffic has gone to zero and is probably a little bit negative.”
American census figures analyzed by the nonpartisan Pew Hispanic Center also show that the illegal Mexican population in the United States has shrunk and that fewer than 100,000 illegal border-crossers and visa-violators from Mexico settled in the United States in 2010, down from about 525,000 annually from 2000 to 2004. Although some advocates for more limited immigration argue that the Pew studies offer estimates that do not include short-term migrants, most experts agree that far fewer illegal immigrants have been arriving in recent years.
