The national and official language in all aspects of the whole territory of North Macedonia and in its international relations is the Macedonian language. Albanian is co-official at a state level (excluding defence, central police and monetary policy) and in local self-government units where speakers are 20% or more. Macedonian belongs to the Eastern branch of the South Slavic language group, while Albanian occupies an independent branch of the Indo-European family of languages. In municipalities where at least 20% of the population is part of another ethnic minority, those individual languages are used for official purposes in local government, alongside Macedonian and Albanian or just Macedonian.
