Its major towns are Lo Borg Sant Dalmatz (Borgo San Dalmazzo), Buscha (Busca), Boves (Bueves) and Draonier (Dronero).
Italian and Piedmontese are spoken by the majority of the people in the area, and the patois is much influenced by both the other two languages.
In the past, in the lower Val Chisone, Waldensian communities were the major part of the population.
The Lower Chisone Valley in the 20th century had a rapid industrial growth, and since then the Waldensian was replaced by Piedmontese in the most bustled villages.
These are the communities which are referred as "Occitan" in the text of the 482/99 Act, and by the agency of linguistic safeguard Chambra d'Oc, even if there was no previous source which supported this appellation.
