Here’s a report released by the Pew Hispanic Center on July 14 showing that during the period from 2000 to 2010 the Mexican-American population increased by 4.2 million as a result of new immigration and by 7.2 million as a result of births.  The study notes that “[t}his is a change from the previous two decades when the number of new immigrants either matched or exceeded the number of births. Between 2006 and 2010, new immigration dropped by 6o%, both because of declining job opportunities and increased immigration enforcement in the United States and recent economic growth in Mexico.

     On the report and these trends, see Julia Preston, “Births Are Outpacing Immigration for Mexican-Americans, Report Says” (NYT July 14, 2011), and Damien Cave, “Better Lives for Mexicans Cut Allure of Going North” (NYT July 6, 2011).
