Compiled by Global Mapping International.
"This dataset consists of polygons covering most of the world, for each language spoken today. The language group locations are accurate for the approximate years of 1990-1995. The data are based on SIL International’s 15th edition of the Ethnologue linguistics database of languages around the world." (Matuszeski and Schneider 2006, p. 11)
Alesina et al. (2016) note (p. 433) that the coverage is limited for Americas and Australia because major immigrant groups are not recorded.
