Canadian Demographic Overview

Zooming out for an overview of BMD trends in Canada, as compiled by Anthropic’s Claude.

The early figures are shaky. Before 1921, Canada had no national system of civil registration.  Everything from 1921 onward comes from Canada’s national vital statistics registration system and is considered reliable.

The sources: Statistics Canada, Historical Statistics of Canada; the 1990 Canada Year Book, “Components of population growth”; Statistics Canada’s 2022 crude-marriage-rate release; and Statistics Canada’s compiled annual vital-statistics series, 1900–2025.
