Mexicans are staying in Mexico or moving back from the US.

Between 2009 and 2014, the Mexican population in the U.S. declined by 1,140,000 as well over 1 million left their wealthy northern neighbor to go back to their country of origin, according to the Mexican National Survey of Demographic Dynamics (ENADID).  One clue to the recent change in the trend is in current perceptions: today one-third of Mexicans believe their standard of living would be no higher north of the border, compared to less than one-quarter who thought so in 2007. And less than half (48%) believe life would be better in the U.S.  The ENADID survey also indicated that family ties had played a large part in the rising numbers of Mexicans moving back south of the border: six in 10 of those who said they had lived in the U.S. five years ago but were back in Mexico as of last year cited reunification with loved ones as the main reason. Just 14% said they had been deported.
