Several Uralic Sámi languages, which are related but not generally mutually intelligible, are traditionally spoken by the Sámi people primarily in Northern Norway and to much lesser extent in some parts of Central Norway. Around 15,000 people have officially registered as Sámi in the Sámi census (''Samemanntallet''), but the number of people of recent Sámi heritage is often estimated at around 50,000 people. The number of people who have some knowledge of Northern Sámi, including as a second language, is estimated at around 25,000 people, but only a minority are native speakers. The other Sámi languages are heavily endangered and spoken by at most a few hundred people. Most people of Sámi heritage are today native speakers of Norwegian as a result of past assimilation policies. Speakers have a right to be educated and to receive communication from the government in their own language in a special ''forvaltningsområde'' (administrative area) for Sámi languages. The Kven minority historically spoke the Uralic Kven language (considered a separate language in Norway, but generally perceived as a Finnish dialect in Finland). Today the majority of ethnic Kven have little or no knowledge of the language. According to the Kainun institutti, "The typical modern Kven is a Norwegian-speaking Norwegian who knows his genealogy." As Norway has ratified the European Charter for Regional or Minority Languages (ECRML) the Kven language together with Romani and Scandoromani language has become officially recognised minority languages.
