COUNTRY - ? / ?
US - American / Americans
UK - English / English
DE - Deutscher / Deutsche

Anyone an idea where to find this? We're trying to find any sort of source for this for weeks now.

  • By the way, this info isn't always objective. For example, the formal (and perhaps proper) demonynm in English is US American

  • obviously we want the natives way of saying it in their language - the super official document paper US American might be not the "common" use case at all. but here is the thing: it seems there isn't any database for this anyway, so whatever form it is is okay... ;)

There is a great internationalization project at


But unfortunately it only includes English demonyms. You might consider expanding the repo if you find a good data source.

      "official":"Federal Republic of Germany",
            "official":"Bundesrepublik Deutschland",
      "Federal Republic of Germany",
      "Bundesrepublik Deutschland"
   "subregion":"Western Europe",
         "official":"Bundesrepublik Deutschland",
         "official":"R\u00e9publique f\u00e9d\u00e9rale d'Allemagne",
         "official":"Njema\u010dka Federativna Republika",
         "official":"Repubblica federale di Germania",
         "official":"Bondsrepubliek Duitsland",
         "official":"Rep\u00fablica Federal da Alemanha",
         "official":"\u0424\u0435\u0434\u0435\u0440\u0430\u0442\u0438\u0432\u043d\u0430\u044f \u0420\u0435\u0441\u043f\u0443\u0431\u043b\u0438\u043a\u0430 \u0413\u0435\u0440\u043c\u0430\u043d\u0438\u044f",
         "official":"Rep\u00fablica Federal de Alemania",
         "official":"Saksan liittotasavalta",
  • see that's the problem - after looking for 2 weeks, there seems to be no single source that lists demonyms and noun and adjective in the countries native language. it's crazy... the data above is still very helpful but still. :)

Like this http://www.iana.org/assignments/language-subtag-registry/language-subtag-registry or this https://en.wikipedia.org/wiki/IETF_language_tag? They called locale codes BTW.

    not the language tags etc. the name of the nationality. example would be US country citizen would be a "American" or "Americans", that's what I want. the nationalities/population/citizen name in their own language. a german citizen is called a Deutscher many are called Deutsche, etc. that for every country and in it's own language. "identifying terms for citizens - noun and adjective"

Maybe these wikidata entries for nationalities? https://www.wikidata.org/wiki/Special:WhatLinksHere/Q231002
