Foreign-born persons include anyone who was not a U.S. citizen at birth. This includes respondents who indicated they were a U.S. citizen by naturalization or not a U.S. citizen. Persons born abroad of American parents or born in Puerto Rico or other U.S. Island Areas are not considered foreign born.
Other survey questions determined the country of birth, year of entry, and citizenship status for the foreign born.
The percentage shown is obtained by dividing the count of foreign-born persons by the total population.
