Introduction to Youth Dependency Ratio

The Youth Dependency Ratio (YDR) is a demographic metric that illustrates the relationship between the youth population (typically aged 0-14) and the working-age population (typically aged 15-64). The result is a percentage that represents the burden placed on the working-age population by the youth population. Understanding YDR is essential for policymakers, economists, and social planners as it impacts decisions on resource allocation, social services, and economic planning.

Parameter usage:

• youthPopulation= Total number of individuals aged 0-14
• workingAgePopulation= Total number of individuals aged 15-64

Example valid values:

• youthPopulation= 3000000
• workingAgePopulation= 5000000

Output:

• YDR= Youth Dependency Ratio percentage

Data validation

The numbers should be greater than zero; otherwise, the function should return an error message. If the workingAgePopulation is zero, it should also return an error.

Example Descriptions

For example, if a country has a youth population of 3,000,000 and a working-age population of 5,000,000, the YDR would be calculated as:

• YDR = (3,000,000 / 5,000,000) × 100
• YDR = 0.6 × 100
• YDR = 60%

This means that for every 100 working-age individuals, there are 60 dependent youths. High YDR values suggest a higher economic burden on the working population, impacting education, healthcare, and social services policies.

Summary

This calculator takes into account the youth population and working-age population to determine the Youth Dependency Ratio, expressed as a percentage. It helps in understanding demographic pressures and planning for future economic and social policies.
