Knowledge of the two official languages is largely determined by geography. Nearly 95% of Quebecers can speak French, but only 40.6% speak English. In the rest of the country, 97.6% of the population is capable of speaking English, but only 7.5% can speak French. Personal bilingualism is most concentrated in southern Quebec and a swath of territory sometimes referred to as the "bilingual belt", which stretches east from Quebec through northern and eastern New Brunswick. It also extends into eastern Ontario, with Ottawa, eastern, and northeastern Ontario holding large populations of Franco-Ontarians. There is also a large French-speaking population in Manitoba. In all, 55% of bilingual Canadians are Quebecers, and a high percentage of the bilingual population in the rest of Canada resides in Ontario and New Brunswick. Statistics Canada collects much of its language data from self-assessments.
