What does the dependency ratio compare?

The dependency ratio is a demographic measure that compares the number of individuals typically considered dependent (those who are not part of the labor force) to those who are considered productive members of society (those who are usually part of the labor force). In this context, the dependency ratio specifically looks at the populations under the age of 15 and over the age of 64, contrasting them with individuals typically aged 15 to 64, who are most likely to be active in the labor market.

By evaluating this ratio, demographers can assess the economic burden on the working-age population. A higher dependency ratio indicates a larger proportion of dependents, suggesting a heavier economic load on the working individuals, while a lower ratio indicates fewer dependents per working-age person. This makes the choice the most accurate representation of what the dependency ratio entails.

The other options do not correctly capture this demographic relationship or present a different theme altogether, such as urban versus rural growth rates or adult-to-child ratios, which do not align with the definition of dependency ratio.
