Latin American diaspora
Over 55 million Hispanic and Latino Americans are residents of the United States, representing 16% of the US population. Hispanic Americans and Latino Americans ( , ) are American citizens who are descendants of immigrants from the Spanish-speaking countries of Latin America and the Iberian peninsula. More generally, it includes all persons in the United States who self-identify as Hispanic or Latino, whether of full or partial ancestry. For the 2010 US census, the American Community Survey, "Hispanic" or "Latino" were those who identified as one of the specific Hispanic or Latino categories listed on the census or ACS questionnaire ("Mexican," "Puerto Rican," or "Cuban") as well as those who indicated that they were "other Spanish, Hispanic, or Latino." The peoples of countries considered as Hispanic or Latino American groups by the Census Bureau were the following: Spain, Mexico, Puerto Rico, Cuba, Dominican Republic, Costa Rica, Guatemala, Honduras, Nicaragua, Panama, El Salvador, Bolivia, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay, and Venezuela. The Census Bureau uses the terms Hispanic and Latino interchangeably. The Census office of the United States excluded Brazilian Americans from the Hispanic and Latino American population (Brazil is part of Latin America, but Portuguese is the official language rather than Spanish). Other US government agencies have slightly different definitions of the term, including Brazilians and other Portuguese-speaking groups.
Hispanic and Latino Americans
Over half of the Hispanic/Latino population is concentrated in the Southwest region, mostly composed of Mexican Americans. California and Texas have some of the largest populations of Mexicans and Central American Latinos in the United States. The Northeast region is dominated by Puerto Ricans and Dominican Americans, having the highest concentrations of both in the country. In the Mid Atlantic region, centered on the DC Metro Area, Salvadoran Americans are the largest of Hispanic groups. Florida is dominated by Cuban Americans and Puerto Ricans. In both the Great Lakes States and the South Atlantic States, Mexicans and Puerto Ricans dominate. Mexicans dominate in the rest of the country, including the Western United States, South Central United States and Great Plains states.
