Enter the percentage of humans under 15 years old and over 65 years old (%) and the percentage of humans in the working class, aged 15-64 (%) into the Dependency Ratio Calculator. The calculator will evaluate and display the Dependency Ratio.

## Dependency Ratio Formula

The following formula is used to calculate the Dependency Ratio.

DR = D / WC
• Where DR is the Dependency Ratio (%)
• D is the percentage of humans under 15 years old and over 65 years old (%)
• WC is the percentage of humans in the working class, aged 15-64 (%)

To calculate the dependency ratio, divide the percentage of humans under 15 and over 65 by the percentage of humans in the 15-64 age bracket.

## How to Calculate Dependency Ratio?

The following example problems outline how to calculate Dependency Ratio.

Example Problem #1:

1. First, determine the percentage of humans under 15 years old and over 65 years old (%).
• The percentage of humans under 15 years old and over 65 years old (%) is given as: 400,000.
2. Next, determine the percentage of humans in the working class, aged 15-64 (%).
• The percentage of humans in the working class, aged 15-64 (%) is provided as: 1,500,000.
3. Finally, calculate the Dependency Ratio using the equation above:

DR = %D / %WC * 100

The values given above are inserted into the equation below and the solution is calculated:

DR = 400,000 / 1,500,000 * 100 = 26.667 (%)

Example Problem #2:

For this problem, the variables required are provided below:

percentage of humans under 15 years old and over 65 years old (%) = 300,000

percentage of humans in the working class, aged 15-64 (%) = 2,000,000
