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.
