In Germany there are some international schools where learning is bilingual. Political campaigning is done in German, and if necessary Turkish or Russian (in parts of the country where this would be an advantage to the party concerned), there are Turkish speaking TV and radio programmes. Of course in the relevant parts of Schleswig Holstein Danish is used as an official language (a curious case only known there). If a language were spoken by more than 5%-10% of the population then it would be declared as an official language (not actually sure about the percentage). Danish is the second political language of Germany ! The same applies to religion and the percentage hurdle. I would not liken Russian to a minority language in the ukraine Frenchie - because in some areas it is the majority language - as French would be in Wallonia (Belgium) or in Valaise (Switzerland). Belgium, Switzerland and Luxembourg are all, officially, multilingual countries because languages are spoken by enough people to ensure state language status. Luxembourg is the most extreme because all primary education is in French, and all secondary education is in German (so the poor kids there are forced to be bilingual from the beginning

). I think you will find by these examples that any western country which had a ''minority'' amounting to 20-30%, or which was a majority language in some administrative areas, would be automatically declared as officially multi lingual. India is the closest example because they have several official languages with the only exception being when the hindu Nationalist nutter party is in power - this is the only case where one language is forced on a multi lingual nation Worldwide as far as I know. China also has several official languages.
