dude, shut the fuck up and get better sources.

"Due to the way the Mexican government sources report data, this analysis uses several overlapping time periods: 2005-2010, for example, and 2009-2014. In addition, migration from Mexico in this analysis includes only those who were born there, while migration to Mexico includes those born in Mexico, the U.S., and elsewhere."

This shit is fucking bullshit and you know it. I m pretty sure this takes into account 0 of those who get in illegaly.
