''Ethnologue: Languages of the World'' (stylized as ''Ethnoloɠue'') 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 International, an American Christian non-profit organization.

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'' isn't ideologically or theologically biased.

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

international standard. Since 2007, ''Ethnologue'' relies only rely on this standard, administered by SIL International, to determine what is listed as a language. Criteria used to be defined as a language are and mutual intelligibility and the existence or absence of a common literature or ethnolinguistic identity. 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 historic research to be done. These lists of names are not necessarily complete.


History

''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. ''Ethnologue'' database was created in 1971 at the

. 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. In 1984, ''Ethnologue'' released a three-letter coding system, called an 'SIL code', to identify each language that it described. This set of codes significantly exceeded the scope of other existing standards, e.g.
ISO 639-1 ISO 639-1:2002, ''Codes for the representation of names of languages—Part 1: Alpha-2 code'', is the first part of the ISO 639 series of international standards for language codes. Part 1 covers the registration of two-letter codes. There are 18 ...

. The 14th edition, published in 2000, included 7,148 language codes. In 2002, ''Ethnologue'' was asked to work with the

and Fante, whereas ''Ethnologue'' considers Twi and Fante to be dialects of a single language (Akan), since they are mutually intelligible. This anomaly resulted because the ISO 639-2 standard has separate codes for Twi and Fante, which have separate literary traditions, and all 639-2 codes for individual languages are automatically part of 639–3, even though 639-3 would not normally assign them separate codes. In 2014, with the 17th edition, ''Ethnologue'' introduced a numerical code for language status using a framework called EGIDS (Expanded Graded Intergenerational Disruption Scale), an elaboration of Fishman's GIDS ( Graded Intergenerational Disruption Scale). It ranks a language from 0 for an international language to 10 for an

Subscribers are mostly institutions: 40% of the world's top 50 universities subscribe to ''Ethnologue'', and it is also sold to business intelligence firms and Fortune 500 companies. The introduction of the paywall was harshly criticized by the community of linguists who rely on ''Ethnologue'' to do their work and cannot afford the subscription The same year, ''Ethnologue'' launched its contributor program to fill gaps and improve accuracy, allowing contributors to submit corrections and additions and to get a complimentary access to the website.

'', Richard Oliver Collin, professor of politics, noted that "''Ethnologue'' has become a standard resource for scholars in the other social sciences: anthropologists, economists, sociologists and, obviously, sociolinguists". According to Collin, ''Ethnologue'' is "stronger in languages spoken by indigenous peoples in economically less-developed portions of the world" and "when recent in-depth country-studies have been conducted, information can be very good; unfortunately ..data are sometimes old". In 2012, linguist Asya Pereltsvaig described ''Ethnologue'' as "a reasonably good source of thorough and reliable geographical and demographic information about the world's languages". She added in 2021 that its maps "are generally fairly accurate although they often depict the linguistic situation as it once was or as someone might imagine it to be but not as it actually is". Linguist George Tucker Childs wrote in 2012 that: "''Ethnologue'' is the most widely referenced source for information on languages of the world", but he added that regarding African languages, "when evaluated against recent field experience thnologueseems at least out of date". In 2014, ''Ethnologue'' admitted that some of its data was out-of-date and switched from a four-year publication cycle (in print and online) to yearly online updates. In 2017,

in response to the lack of a comprehensive language bibliography, especially in ''Ethnologue''. In 2015, Hammarström reviewed the 16th, 17th, and 18th editions of ''Ethnologue'' and described the frequent lack of citations as its only "serious fault" from a scientific perspective. He concluded: "''Ethnologue'' is at present still better than any other nonderivative work of the same scope. tis an impressively comprehensive catalogue of world languages, and it is far superior to anything else produced prior to 2009. In particular, it is superior by virtue of being explicit." According to Hammarström, as of 2016, ''Ethnologue'' and Glottolog are the only global-scale continually maintained inventories of the world's languages. The main difference is that ''Ethnologue'' includes additional information (such as speaker numbers or vitality) but lacks systematic sources for the information given. In contrast, Glottolog provides no language context information but points to primary sources for further data. Contrary to ''Ethnologue'', Glottolog doesn't run its own surveys, but it uses ''Ethnologue'' as one of its primary sources. As of 2019, Hammarström uses ''Ethnologue'' in his articles, noting that it "has (unsourced, but) detailed information associated with each speech variety, such as speaker numbers and map location". In response to feedback about the lack of references, ''Ethnologue'' added in 2013 a link on each language to language resources from the Open Language Archives Community (OLAC) ''Ethnologue'' acknowledges that it rarely quotes any source verbatim but cites sources wherever specific statements are directly attributed to them, and corrects missing attributions upon notification. The website provides a list of all of the references cited. In her 2021 review, Shobhana Chelliah noted that Glottolog aims to be better than ''Ethnologue'' in language classification and genetic and areal relationships by using linguists' original sources.
