Aging Crunch

Dependency Ratio: The dependency ratio measures the number of dependents (children and elderly) compared to the working-age population. A high dependency ratio indicates that there are more dependents relative to workers.

Demographic Transition: Demographic transition refers to the process of change in birth rates and death rates as societies move from pre-industrial to industrialized economies. It is often associated with shifts in population age structure.

Social Security: Social security is a government program that provides financial support for retired and disabled individuals. In an aging crunch scenario, social security systems may face challenges due to insufficient funds or strain on resources.
