(5) A continuing decline in Mexicans moving to the United States is being attributed to stronger immigration enforcement efforts and the weak U.S. job market.  Two American universities released a report Wednesday indicating a 57 percent decrease in immigrants crossing the border between 2003 and 2012, including a four-year period when less than a million people traveled between Mexico and the United States.
    (6) According to the report, possible factors include a declining Mexican birth rate increased border security, and more detentions of illegal migrants in the United States. Other important causes were the slowing U. S. economy when compared to Mexico’s and a declining U. S. construction industry.
