Here's what we know:
* The majority of Quebecers speak French as their first language. This is supported by Statistics Canada data, which shows that French is the mother tongue of around 80% of the population.
* French is the official language of Quebec. This means it's used in government, education, and public life.
* English is also spoken in Quebec, particularly in the Montreal region. This is due to historical immigration patterns.
While there's no single, definitive percentage, it's safe to say that the vast majority of Quebecers are French speakers.
