Population of Montréal in Canada 2021, by mother tongue

The source adds the following information: "Mother tongue refers to the first language learned at home in childhood and still understood by the person at the time the data was collected. If the person no longer understands the first language learned, the mother tongue is the second language learned. For a person who learned more than one language at the same time in early childhood, the mother tongue is the language this person spoke most often at home before starting school. The person has more than one mother tongue only if they learned these languages at the same time, and still understands them. For a child who has not yet learned to speak, the mother tongue is the language spoken most often to this child at home. A child who has not yet learned to speak has more than one mother tongue only if these languages are spoken to them equally often so that the child learns these languages at the same time."
