Sixty-five percent of the Nation’s 50.7 million Latinos self-identify as being of Mexican origin, according to tabulations of the 2010 American Community Survey (ACS) released Wednesday by the [Pew Hispanic Center.](http://www.pewhispanic.org/2012/06/27/the-10-largest-hispanic-origin-groups-characteristics-rankings-top-counties/) No other Latino subgroup rivals the size of the Mexican-origin population, according to the report. Puerto Ricans, the nation’s second largest Hispanic origin group, make up just 9% of the total Hispanic population in the 50 states and the District of Columbia. Mexicans, Puerto Ricans, Cubans, Salvadorans, Dominicans, Guatemalans, Colombians, Hondurans, Ecuadorians and Peruvians make up 92% of the U.S. Latino population.
