The two statistics seem to contradict each other. And yet in the cruel, upside down world of immigration and border enforcement, both are true. Net immigration into the country from Mexico has all but screeched to a halt, but those who are trying to enter into the country are dying in ever higher numbers in the middle of their journeys. The United States is witnessing two simultaneous dynamics. [Pew Research Center](http://pewresearch.org/pubs/2250/mexican-immigration-immigrants-illegal-...), responsible for detailing the first finding this spring, found that due to increasingly harsh border enforcement and the ongoing economic recession in the U.S. net migration may have even hit negative rates. Meanwhile, the numbers of bodies found in the desert just this year by border agents have reached almost 150, a 200 percent jump from the last fiscal year, [NBC](http://openchannel.nbcnews.com/_news/2012/10/09/14300178-deadly-crossing...) reported today. "[W]hile fewer are crossing, more are dying," write reporters Hannah Rappleye and Lisa Riordan Seville.
