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. 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.
