According to a new survey from the Pew Research Center, more Mexican immigrants have returned to Mexico from the U.S. than have migrated here since 2009. The study shows the overall flow of Mexican immigration into the U.S. is at its lowest since the 1990s. Additionally, Pew found the Mexican-born population in the U.S. declined to 11.7 million in 2014, down from 12.8 million in 2007. A majority of those who’ve left the U.S. since 2009 left on their own accord, and 61 percent of those who’ve returned to Mexico cited family reunification as their main reason. Only 14 percent said their departure was due to deportation. Many who left cited the recession and lack of jobs as a reason.
