Brittany and its people are counted as one of the six Celtic nations. Ethnically, along with the Cornish and Welsh, the Bretons are Celtic Britons. The actual number of Bretons in Brittany and France as a whole is difficult to assess as the government of France does not collect statistics on ethnicity. The population of Brittany, based on a January 2007 estimate, was 4,365,500. It is said that, in 1914, over 1 million people spoke Breton west of the boundary between the Breton- and Gallo-speaking region, roughly 90% of the population of the western half of Brittany. In 1945, it was about 75%, and today, in all of Brittany, at most 20% of Bretons can speak Breton. Brittany has a population of roughly four million, including the department of Loire-Atlantique, which the Vichy government separated from historical Brittany in 1941. Seventy-five percent of the estimated 200,000 to 250,000 Breton speakers using Breton as an everyday language today are over the age of 65.
