What is "ethnologue"

Ethnologue: Languages of the World is a web-based publication that contains statistics for 7,457 languages in its 19th edition, which was released in 2016. Of these, 7,097 are listed as living and 360 are listed as extinct. Up until the 16th edition in 2009, the publication was a printed volume. Ethnologue provides information on the number of speakers, location, dialects, linguistic affiliations, availability of the Bible in each language and dialect described, and an estimate of language viability using the Expanded Graded Intergenerational Disruption Scale (EGIDS). The publication is well respected and widely used by linguists.
