Which country is the most populous as of 2024?

India was the world’s most populous country as of 2024, with an estimated population of about 1.45 billion people. It overtook China around 2023 and has remained at the top of global population rankings.

India’s population reflects centuries of settlement across a varied landscape, from the fertile Indo-Gangetic Plain to the densely populated coasts and river deltas. The country contains more than one-sixth of humanity, although its people are unevenly distributed: the Himalayan regions and parts of the Thar Desert are far less crowded than the northern plains and major urban corridors.

A common mix-up is assuming China must still rank first because it held that position for most recent history. China’s population has started to decline, while India continued growing, even though India’s fertility rate has also fallen substantially. Population rankings depend on estimates because no country conducts a perfectly real-time global census; different agencies may publish slightly different totals.

India’s demographic scale affects nearly every global comparison, including labor markets, food demand, urbanization, elections, and climate policy. Its population is also relatively young compared with several other major powers, although the country is aging gradually.
