In 1914 reportedly 90% (about 1 million) of the population of the western half of Brittany spoke Breton. In 1945 it was about 75%, and today, in all of Brittany the most optimistic estimate would be that 20% of Bretons can speak Breton. Brittany has a population of roughly 4 million, including the department of Loire-Atlantique separated from official Brittany in 1941.
Breton is spoken in France, Europe.
