The Modern Language Association today inaugurated a significantly enhanced version of its Language Map, which provides “previously unavailable information about the age, English-language speaking ability, and locations of speakers for over 300 languages in the United States,” according to an MLA press release.

The new version, which supersedes a 2004 edition, draws on data from the 2000 Census about the “more than 47,000,000 Americans who speak languages other than English at home.” Users can view maps that track the number of a language’s speakers in any given state, city, town, county, or ZIP code. The site also allows users to “display extensive language-data spreadsheets or compact ‘Language Snapshots,’ which encapsulate information about languages or locales in a single frame.”

The map allows “a scholar of Native American language, for instance, to search for the numbers and ages of home speakers of Navajo, Keres, Zuni, Tewa, Tiwa, and Towa in New Mexico or a fifth grader to search for the percentage of individuals in the state who at home can speak Spanish, French, Korean, Tagalog, or any other language,” according to Rosemary G. Feal, executive director of the MLA.

J. Michael Holquist, the organization’s vice president and a professor of comparative literature and Slavic at Yale University, said that the project demonstrates how the United States, “with the exception of Papua New Guinea, is the country in the world with the greatest diversity of languages.”
