In a historic shift, the flow of Mexicans leaving the United States has surpassed that of Mexicans arriving, and it’s at its lowest since the 90s. According to a study of the Pew Research Center, more than a million Mexicans returned to their native land compared to 870,000 that migrated to the United States between 2009 and 2014. Contributing factors are heightened border militarization, the United States’ slow recovery from the 2008 recession, and family matters. Over the past 50 years, 16 million Mexicans have migrated to the U.S. By 2010, the flow had stabilized and is now in reverse. Clayton Conn reports from Mexico City for teleSUR.
