Most popular edition of Wikipedia by country. In grayed-out countries, the "national-language" edition is usually the most popular, but there are exceptions: for example, Afghanistan has Persian Wikipedia as the most popular (there is no Dari Wikipedia).
The Meta-Wiki language committee manages policies on creating new Wikimedia projects. To be eligible, a language must have a valid ISO 639 code, be "sufficiently unique", and have a "sufficient number of fluent users".[5]
Each Wikipedia project has a code, which is used as a subdomain of wikipedia.org. The codes mostly conform to ISO 639-1 two-letter codes or ISO 639-3 three-letter codes, with preference given to a two-letter code if available.[14] For example, en stands for English in ISO 639-1, so the English Wikipedia is at en.wikipedia.org.
