Immigration is central to the growth and identity of the Hispanic population. Almost all of the project's research, regardless of topic, includes separate tabulations of data for U.S.-born and foreign-born Hispanics. Research on immigration focuses on the unauthorized population, overall trends in immigration and public attitudes towards immigrants and immigration policy.
Also see our statistical portraits, state and county databases, demographic profiles and Census 2010 tables for data on the characteristics of the Latino and foreign-born populations in the United States.
