In April, the Pew Research Center found that from 2005-2010 the net Mexican migration to the U.S. was essentially zero. That data suggested that perhaps the decades-long surge of migration to the U.S. from Mexico was coming to an end due to an economic recession and a massive federal enforcement presence at the border.
But this year migration flows appear to be changing again according to a joint study by the University of Southern California's Tomás Rivera Policy Institute and El Colegio de la Frontera Norte in Mexico.
"As the economy here has partially recovered the flows have stabilized and there's some tentative signs of increase and the potential for increase," said Roberto Suro, who co-wrote the study.
Researchers surveyed Mexican migrants at bus stations, airports and border crossings. They cite an increase in the amount of remittances to Mexico and an improved employment rate for Mexicans living in the United States.
