Click on a language to see the most current data available from the American Community Survey or Census 2000. Data are given for states in which a language is reported, the ages of speakers, and their reported ability to speak English. Data are not available for 2010 or 2000 for all languages. This list, formulated by the Census Bureau, combines languages reported to census enumerators with those languages identified as spoken in the United States in C. F. Voegelin and F. M. Voegelin’s Classification and Index of the World’s Languages (New York: Elsevier, 1977). To find out more about any language on this list, visit Ethnologue, an online index of the world’s languages.
