World Population in 2024

Global Population Overview

The world's population reached 8.12 billion in 2024, with India (1.45B) and China (1.41B) together accounting for over a third of humanity. India surpassed China as the most populous country in 2023, a historic milestone reflecting decades of different fertility and population policies. The top 10 most populous countries contain over 4.4 billion people — more than half the global total.

Global population growth has slowed dramatically from its peak of over 2% annually in the late 1960s to approximately 1.1% today. This deceleration is driven by falling fertility rates across virtually every region — total fertility rates have dropped below replacement level (2.1 children per woman) in all developed countries and many developing ones. Sub-Saharan Africa remains the only region with high fertility, but rates are declining there too. The UN projects global population will peak around 10.4 billion in the 2080s before slowly declining.

Population data is critical for economic analysis because it determines labor force size, consumer market potential, and dependency ratios. Countries experiencing rapid population decline (Japan, South Korea, much of Eastern Europe) face challenges including shrinking workforces and rising pension costs. Countries with growing populations (India, Nigeria, Ethiopia) have the potential for a "demographic dividend" — if they can productively employ their youth.
