First of all, Hispanic is not a "race,." as leftists would have you believe. There are black, brown, and white Hispanics. The use of the ethnic group "Hispanic" as a similie for "brown" is entirely tendentious.
Secondly, the figures are not mine, they are from the 2008 U.S. census as cited by Jeff Jacoby, hardly a right winger. Read the article. Links are provided directly to the pertinent census data.
Thirdly, Google has a lot of left leaning nonsense, which is hardly scientific in nature.
