Population and the Economy in detail

A country's population affects its economy. The size and age structure decide the labour force, demand for goods, and costs of services such as schools, healthcare and pensions. A young population can provide a future workforce but need education and jobs, while an ageing population has more retired people, increasing healthcare and pension costs and putting pressure on fewer workers.

The dependency ratio compares dependants (young and old) with the working-age population. Migration can fill labour shortages and add skills. Birth rates, life expectancy and migration shape these trends, and governments plan policies on pensions, immigration and family support.
