MLA Language Map: A Map of Languages in the United States.
"The MLA Language Map is for students, teachers, and anyone interested in learning about the linguistic and cultural composition of the United States. The Language Map uses aggregated data from the 2006–10 American Community Survey (ACS) to display the locations and numbers of speakers of twelve languages commonly spoken in the United States. Data from the MLA's 2016 census of enrollments in languages other than English indicate where these languages are taught in colleges and universities. The Language Map Data Center provides information about over three hundred languages spoken in the United States, using data from the 2006–10 ACS, ACS 2005, and the 2000 US Census. Comparative tables and graphs provide a snapshot of changes between 2000 and 2010 in American language communities, showing speakers’ ages and ability to speak English." [Home page]
