Age Dependency Ratio Calculator

Calculate old-age, young-age, and total dependency ratios from population age structures. Total dependency ratio = (population aged 0–14 + 65+) / (population aged 15–64) × 100.

How It Works

Calculate old-age, young-age, and total dependency ratios from population age structures. Total dependency ratio = (population aged 0–14 + 65+) / (population aged 15–64) × 100

Each component has a specific meaning:

  • Population age structures — The population age structures recorded for the scenario being assessed.

Note: Interpret the dependency ratio result against the thresholds and context described above.

How to Use

Enter the population age structures for the scenario you are assessing. Calculate old-age, young-age, and total dependency ratios from population age structures. Total dependency ratio = (population aged 0–14 + 65+) / (population aged 15–64) × 100. Use the dependency ratio result to inform your calculation.
