Autonomous communities of Spain
Spanish legislation, most notably in the Statutes of Autonomy of the bilingual communities, use the term "own language", or "language proper to a community", to refer to a language other than Spanish that originated or had historical roots in that particular territory. The Statutes of Autonomy of the respective autonomous communities have declared Basque the language proper to the Basque Country and Navarre, Catalan the language proper to Catalonia, the Balearic Islands and the Valencian Community—where it is historically, traditionally and officially known as Valencian—and Galician to be the language proper to Galicia. There are other protected regional languages in other autonomous communities. As a percentage of total population in Spain, Basque is spoken by 2%, Catalan/Valencian by 17%, and Galician by 7% of all Spaniards. A 2016 Basque Government census revealed 700,000 fluent speakers in Spain (51,000 in Basque counties in France) and 1,185.000 total when passive speakers are included.
Standard Spanish
Given that a neutral Spanish for all Spanish-speakers is impossible, there are four established standardized "Spanishes" used in translations and, more recently, in film-dubbing by some companies: (1) Castilian or Peninsular Spanish for Spain; (2) River Plate Spanish for Uruguay, Paraguay and Argentina (using "voseo"); (3) Mexican Spanish for the United States, Canada, Mexico, Central America (even though this last region is largely "voseante"), and the rest of Spanish-speaking America); (4) the Spanish of international organisations like the United Nations, the Organisation of American States and their respective specialised bodies. Naturally UN Spanish differs from OAS Spanish, because Spain is not a full member of the latter organisation, and thus its influence is weak. But Spain was refused membership in the UN when it was founded in 1945, since Spain was a dictatorship. Although it remained a dictatorship, it was eventually admitted in 1956. However, by then UN Spanish had already been established by Spanish-American diplomats and translators.
