While the number of births to Hispanic families grew dramatically through 2007, in 2008 a sharp deline started in all birth rates, with Hispanics again leading the way. See articles like "Hispanic birth rate plummeting in the U.S.," online at http://www.examiner.com/women-s-health-in-los-angeles/hispanic-birth-rate-plummeting-the-u-s . This November 28, 2011 article, and others like it, indicate that the lowering Hispanic birth rate has continued since 2009.  The 2010 total birth number from Dallas County of 39,712 confirms that all numbers are probably dropping.  (Information is welcomed about where to locate more recent birth numbers for Dallas County.  Has this drop in birth numbers continued in 2011?)
