Working age population in the United Kingdom

This indicator measures the share of the population aged 15 to 64 within the resident population, encompassing all inhabitants regardless of their legal status or citizenship. Commonly defined as the working-age population, this cohort represents the primary engine of economic activity, providing the essential labor supply required for the production of goods and services.
A larger share of working-age individuals expands an economy’s productive capacity and tax base. Conversely, a shrinking share increases the dependency ratio - the proportion of those aged under 15 and over 64 relative to the working-age population - necessitating higher labor productivity to sustain growth.
