Only three U.S. counties with no foreign-born residents in 2010 reported a 100 percent native population in 2019, according to a Social Explorer analysis of newly released 2015-19 American Community Survey data. The three – Blaine County, Neb.; Clay County, W.Va.; and Issaquena County, Miss. – were among 18 counties with no foreign-born residents in 2019, down from 22 all-native-born counties in 2010.
Nationwide, the percentage of native-born residents fell to 86.5 percent, a slight dip from the 87.3 percent reported in 2010. Miami-Dade, Fla., was the only county to record a minority of native-born residents, with 46.3 percent of its population born in the United States.
