Asturian is part of a wider linguistic group, the Astur-Leonese languages. The number of speakers is estimated at 100,000 (native) and 450,000 (second language). There are three main variants in the Astur-Leonese language family: Western, Central, and Eastern. For historical and demographic reasons, the standard is based on Central Asturian.
