Nearly half of U.S.-born Latinos are younger than 18: “Hispanics are the youngest major racial or ethnic group in the United States. About one-third, or 17.9 million, of the nation’s Hispanic population is younger than 18, and about a quarter, or 14.6 million, of all Hispanics are Millennials (ages 18 to 33 in 2014), according to a Pew Research Center analysis of U.S. Census Bureau data.
