There has been much discussion in the US presidential campaign about immigration, especially from Mexico. Trump has proposed a wall for the 2000 mile border. Different types of fences are on about a third of the border as it stands today.
However, as this Great Graphic, from Pew Research shows, Mexican immigrants may have been a problem previously, but for the past decade (2005-2014) more Mexicans have left the US than entered (hat tip to Philip Bump).
In 1995-2000, there were a little more than two and a quarter million Mexicans that migrated to the US. In the 2005-2014 period 160k net have returned to Mexico.
