Mexico City, June 3 (teleSUR-RHC)-- A darling of the U.S. anti-immigrant right is facing criticism over false claims that “America has already taken in one-fourth of Mexico's entire population."

Ann Coulter’s, author of the new book Adios America, based her claims on a 2013 analysis of the census data by Pew Research Center, in which more than 30 million people in the U.S. said that they were of Mexican roots.

The population of Mexico is 120 million, with one-fourth of that amounting to 30 million people. But the Pew research that Coulter used for her flawed conclusion clearly states that “Mexicans in this statistical profile are people who self-identified as Hispanics of Mexican origin; this means either they are Mexican immigrants or they trace their family ancestry to Mexico.

Mexicans are the largest population of Hispanic origin living in the United States, accounting for nearly two-thirds (64.6per cent) of the U.S. Hispanic population in 2011.”

While Coulter seems to have utterly misread the data and made up her own conclusions, it is also clear that she did not take the time to read through the relatively short analysis. The analysis clearly indicates that about two-thirds of U.S. citizens with Mexican ancestry were born in the U.S. Thus, they were never part of Mexico’s population.

Also, according to the Census Bureau, about 10.5 million people of Mexican heritage come from families in which both parents were born in the U.S.. Coulter's conclusion makes no difference between a person whose parents or grandparents had immigrated to the U.S. decades ago and a person who entered the country yesterday. For Coulter, they are all part of the population in Mexico, and never U.S. citizens.
