Dependency Ratio

Introduction to Dependency Ratio

The dependency ratio is a demographic measure that shows the number of dependents (aged under 15 or over 64) to the total working-age population (aged 15 to 64). The result is expressed as a percentage and is used to assess the pressure on the working population to support non-working age groups.

Parameter usage:

• DP = dependent population (under 15 or over 64)
• WAP = working-age population (15 to 64)

Output:

• DR = dependency ratio in percentage

Data validation

The numbers should be greater than or equal to zero. Additionally, the working-age population should not be zero.

Summary

This formula provides a metric for understanding the proportion of the population that is dependent on the working-age population.
