Mapping Language Usage

Dr. Huffman has classified the languages of the Ethnologue into broader groupings following Merritt Ruhlen’s A Guide to the World’s Languages (published 1987, 1991 by Stanford University Press), and has produced as series of maps of language phyla and families using this classified data and GMI’s World Language Mapping System and Seamless Digital Chart of the World geographic datas sets.

PDF versions of the maps available for download, as are Dr. Huffman’s data and ArcGIS project files.
