How to read this measure Estimates are final intercensal up to 2020, final postcensal for 2021, updated postcensal for 2022, 2023 and 2024, and preliminary postcensal for 2025. Northwest Territories and Nunavut estimates are separate from 1991; earlier figures combine them. ## How this answer was calculated The headline compares the first and last observations shown. Absolute change is the last source value minus the first; relative change is (last ÷ first − 1) × 100. Intermediate observations remain visible in the chart and exact values. This is descriptive and does not identify causes. ## Source and provenance - Official source: [Statistics Canada table 17-10-0005-01]() - Table title: Population estimates on July 1, by age and gender - Dataset identifier: 17100005 - Canonical human-readable answer: - Province and territory comparison: - Interpretation policy: this answer describes the selected observations; it does not infer causation. - Source acknowledgement: Adapted from Statistics Canada, Population estimates on July 1, by age and gender, 2025-09-24.
