The Pew Hispanic Center's latest report – The Mexican-American Boom: Births Overtake Immigration — is the latest report to conclude that illegal immigration from Mexico into the U.S. has slowed.

The report says the number of people leaving Mexico declined by 60 percent from 2006 to 2010, based on analysis of Mexican government data.

"This is likely a result of recent developments in both the U.S. and Mexico. On the U.S. side, declining job opportunities and increased border enforcement may have made the U.S. less attractive to potential Mexican immigrants," the Pew Hispanic Center wrote. "And in Mexico, recent strong economic growth may have reduced the “push” factors that often lead Mexicans to emigrate to the U.S."

In February, the Pew Hispanic Center issued a report that showed the estimated number of illegal immigrants living in the U.S. had dropped to 11.2 million nationwise since reaching a peak of 12 million in 2007.

If you didn't already see it, The New York Times' Mexico City coorespondent Damien Cave recently wrote a fascinating story that argues that the "push" factors in Mexico have decreased:

It's a long, in-depth story that is well worth your time. Here is the lead:

"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."

The Border Patrol's apprehensions figures, albeit a flawed statistic, also show a decrease in migration from Mexico.

Interestingly enough, apprehensions of Mexican illegal immigrants at the U.S.-Mexico border has decreased by 60 percent — the same percentage dip that the new Pew Hispanic Center report found using Mexican government data for people leaving annually.

The Border Patrol registered nearly 397,000 apprehensions of Mexican illegal immigrants in fiscal year 2010, down from 974,000 in fiscal year 2006, U.S. government data shows.
