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.
Mixed-blood
The most recent Hispanic immigrants, who arrived during mid-century until today, have mainly identified as mestizo or Amerindian. They have come from Mexico, Central and South America. Of the over 35 million Hispanics counted in the Federal 2000 Census, the overwhelming majority of the 42.2% who identified as "some other race" are believed to be mestizos—a term not included on the US Census but widely used in Latin America. Of the 47.9% of Hispanics who identified as "White Hispanic", many acknowledge possessing Amerindian ancestry, as do many European Americans who identify as "White". Hispanics identifying as multiracial amounted to 6.3% (2.2 million) of all Hispanics; they likely included many mestizos as well as individuals of mixed Amerindian and African ancestry.
