Hispanics of Mexican, Puerto Rican, and Cuban origin or descent remain the nation's three largest Hispanic country-of-origin groups, according to the 2010 U.S. Census. However, while the relative position of these three groups has remained unchanged since 2000, the next four Hispanic sub-groups grew faster during the decade.
Hispanics of Salvadoran origin, the fourth largest Hispanic country-of-origin group grew by 152% since 2000. The Dominican population grew by 85%, the Guatemalan population by 180% and the Colombian population by 93%. Meanwhile, the Cuban and Puerto Rican populations grow more slowly—44% and 36% respectively.
Despite their No. 1 status, Mexicans are not the dominant Hispanic origin group in many of the nation's metropolitan areas. Among the Miami metropolitan area's 1.5 million Hispanics, half are Cuban. In the New York-Northeastern New Jersey metropolitan area, 29.4% of Hispanics are of Puerto Rican origin and 19.7% are of Dominican origin. In the Washington, DC metropolitan area, Salvadorans are the largest group, comprising one-third of the area's Hispanics.
