Comparison
Population estimates are not exact counts. They may be revised as ONS incorporates improved evidence. Age groups intentionally overlap: school-age residents are within children, and young adults overlap the working-age group.

Methodology and limitations
Current share
The selected age-group population as a percentage of the council's total 2025 population.
Population change
Percentage change in the selected age group between 2021 and 2025. “Lowest” is used because some groups grew everywhere.
Eligibility
Councils require at least 10,000 residents in both years. Change rankings also require at least 500 people in the starting cohort.
