Old-Age Dependency Ratio

Introduction to Old-Age Dependency Ratio Calculator

The old-age dependency ratio is a measure of the population aged 65 and over (old population) as a percentage of the working-age population (usually defined as ages 15-64). The formula calculates the percentage by dividing the number of elderly people by the number of people in the working-age population, then multiplying the result by 100. A higher old-age dependency ratio indicates a larger proportion of the population is elderly, relative to the working-age population.

Parameter usage:

• oldPopulation = number of population aged 65 and over
• workingPopulation = number of people in the working-age population (ages 15-64)

Example valid values:

• oldPopulation = 20000
• workingPopulation = 80000

Output:

• oldAgeDependencyRatio = old-age dependency ratio in percentage

Data validation

The numbers should be greater than zero.

Summary

This calculator helps in understanding the dependency ratio of elderly people on working-age population and is useful for social and economic planning.
