Dependency Ratio Formula
The following formula is used to calculate the Dependency Ratio.
DR = (D / WC) \times 100
- Where DR is the Dependency Ratio (dependents per 100 working-age people)
- D is the dependent population (ages 0–14 and 65+) (people, or % of total population)
- WC is the working-age population (ages 15–64) (people, or % of total population)
To calculate the dependency ratio, divide the number (or percentage) of people aged 0–14 and 65+ by the number (or percentage) of people aged 15–64, then multiply by 100.
How to Calculate Dependency Ratio?
The following example problems outline how to calculate Dependency Ratio.
Example Problem #1:
- First, determine the dependent population (ages 0–14 and 65+).
- The dependent population is given as: 400,000 people.
- Next, determine the working-age population (ages 15–64).
- The working-age population is provided as: 1,500,000 people.
- 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 dependents per 100 working-age people
Example Problem #2:
For this problem, the variables required are provided below:
Dependent population (ages 0–14 and 65+) = 300,000
Working-age population (ages 15–64) = 2,000,000
Test your knowledge using the equation and check your answer with the calculator above.
DR = D / WC × 100 = ?
