Ethnologue

Ethnologue: Languages of the World is an annual reference publication in print and online that provides statistics and other information on the living languages of the world. It is the world's most comprehensive catalogue of languages. It was first issued in 1951 and is now published by SIL Global, an American evangelical Christian non-profit organization.

Ethnologue has been published by SIL Global (formerly known as the Summer Institute of Linguistics), a Christian linguistic service organization with an international office in Dallas, Texas. The organization studies numerous minority languages to facilitate language development, and to work with speakers of such language communities in translating portions of the Bible into their languages. Despite the Christian orientation of its publisher, Ethnologue is not ideologically or theologically biased.

Ethnologue includes alternative names and autonyms, the number of L1 and L2 speakers, language prestige, domains of use, literacy rates, locations, dialects, language classification, linguistic affiliations, typology, language maps, country maps, publication and use in media, availability of the Bible in each language and dialect described, religious affiliations of speakers, a cursory description of revitalization efforts where reported, intelligibility and lexical similarity with other dialects and languages, writing scripts, an estimate of language viability using the Expanded Graded Intergenerational Disruption Scale (EGIDS), and bibliographic resources. Coverage varies depending on language. For instance, as of 2008, information on word order was present for 15% of entries while religious affiliations were mentioned for 38% of languages. According to Lyle Campbell "language maps are highly valuable" and most country maps are of high quality and user-friendly.

Ethnologue gathers information from SIL's thousands of field linguists, surveys done by linguists and literacy specialists, observations of Bible translators, and crowdsourced contributions. SIL's field linguists use an online collaborative research system to review current data, update it, or request its removal. SIL has a team of editors by geographical area who prepare reports to Ethnologue's general editor. These reports combine opinions from SIL area experts and feedback solicited from non-SIL linguists. Editors have to find compromises when opinions differ. Most of SIL's linguists have taken three to four semesters of graduate linguistics courses, and half of them have a master's degree. They're trained by 300 PhD linguists in SIL.

The determination of what characteristics define a single language depends upon sociolinguistic evaluation by various scholars; as the preface to Ethnologue states, "Not all scholars share the same set of criteria for what constitutes a 'language' and what features define a 'dialect'." The criteria used by Ethnologue are mutual intelligibility and the existence or absence of a common literature or ethnolinguistic identity. The number of languages identified has been steadily increasing, from 5,445 in the 10th edition (in 1984) to 6,909 in the 16th (in 2009), partly due to governments recognizing mutually intelligible varieties as separate languages, and partly due to SIL establishing new Bible translation needs. Ethnologue codes were used as the base to create the new ISO 639-3 international standard. Since 2007, Ethnologue relies only on this standard, administered by SIL International, to determine what is listed as a language.

In addition to choosing a primary name for a language, Ethnologue provides listings of other name(s) for the language and any dialects that are used by its speakers, government, foreigners and neighbors. Also included are any names that have been commonly referenced historically, regardless of whether a name is considered official, politically correct or offensive; this allows more complete historical research to be done. These lists of names are not necessarily complete.

Ethnologue was founded in 1951 by Richard S. Pittman and was initially focused on minority languages, to share information on Bible translation needs. The first edition included information on 46 languages. Hand-drawn maps were introduced in the fourth edition (1953). The seventh edition (1969) listed 4,493 languages. In 1971, Ethnologue expanded its coverage to all known languages of the world.

The Ethnologue database was created in 1971 at the University of Oklahoma under a grant from the National Science Foundation. In 1974 the database was moved to Cornell University. Since 2000, the database has been maintained by SIL International in their Dallas headquarters. In 1997 (13th edition), the website became the primary means of access.
