Trends in Working Age Population Percentage in Nigeria from 1990 to 2022

The working-age population in Nigeria experienced steady growth between 1990 and 2022. Starting at 52% in 1990, the percentage rose consistently, reaching 53.5% in 2000. After a brief period of stability and minor declines from 2000 to 2010, it started to rise again, reaching 54% in 2022. Factors contributing to this growth include Nigeria's high fertility rate, which has driven a larger labor force over time, and improvements in healthcare. The increase also reflects broader demographic changes as the population ages, gradually expanding the share of individuals within working age.
