Population Size and Global Development
Population is one of the most fundamental indicators in global data analysis. A country's population determines its labor supply, domestic market size, resource consumption, and political weight on the global stage.
India is now the world's most populous country, having surpassed China in 2023. While both nations are economic powerhouses, China has a significantly higher GDP per capita and HDI score, reflecting decades of industrial and economic policy differences.
Notably, most of the world's most populous nations are concentrated in Asia and Africa. Africa's population is growing the fastest and is projected to become the world's most populous continent by the end of this century.
