Among the 50.7 million Hispanics in the United States, nearly two-thirds (65%), or 33 million, self-identify as being of Mexican origin, according to tabulations of the 2010 American Community Survey (ACS) by the Pew Hispanic Center, a project of the Pew Research Center. No other Hispanic subgroup rivals the size of the Mexican-origin population. 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.
- Nearly three-in-four (74%) Hispanics are U.S. citizens, compared with 93% of the entire U.S. population.
- Those born in Puerto Rico are U.S. citizens by birth, and fully 99% of Puerto Ricans hold citizenship. Cubans (74%) and Mexicans (73%) have the next highest shares of U.S. citizens.
- Hondurans (47%) and Guatemalans (49%) are the only groups among the 10 most populous Hispanic origin groups in which less than half of their populations are U.S. citizens. Hispanics of Salvadoran origin (55%) are the third least likely group to be U.S. citizens.
Cubans are the third-largest population of Hispanic origin living in the United States, accounting for 3.7% of the U.S. Hispanic population in 2010.
