About this ranking

People aged 5 and over who speak Spanish 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 or Hispanic origin. Hispanic origin is hispanic_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.
