What is the mean of age dependency rate?

The age dependency ratio is a measure that compares the number of dependents (individuals typically aged 0-14 and those aged 65 and older) to the working-age population (usually defined as individuals aged 15-64). It is expressed as a percentage or ratio, indicating how many dependents there are for every 100 working-age individuals. A higher age dependency ratio suggests greater pressure on the working-age population to support dependents, affecting economic productivity and social services. The mean age dependency rate can vary significantly between countries and regions, reflecting demographic trends and social policies.
