About this ranking

People aged 5 and over who speak a language other than English at home, as a percentage of all people aged 5 and over. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

Measures the language used at home, not English ability: most people in this group also speak English. Spanish speakers are shown separately in spanish_at_home_share.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
