Which Countries Will Be the Most Populated in 2050?
The UN Population Division's 2024 medium-variant projections show major rank shifts between now and 2050:
- India stays #1, peaking around 1.7 billion in the early 2060s
- China drops to #2 and continues falling — projected to ~1.3 billion by 2050 as its population ages and shrinks
- Nigeria surges past the U.S. to become #3 — projected to ~400 million by 2050
- United States drops to #4 — projected to ~380 million by 2050
- Pakistan overtakes Indonesia for #5
- DR Congo enters the top 10 with ~200 million
The story of 21st-century population growth is overwhelmingly an African story. Sub-Saharan Africa is projected to contribute roughly 56% of all global population growth between 2025 and 2050.

When will Nigeria become the third most populated country?
The UN Population Division projects Nigeria will overtake the United States to become the world's third most populated country sometime between 2045 and 2050.
Why did China lose its #1 population spot?
China's population has been declining since 2022 due to its persistently below-replacement fertility rate (~1.0 births per woman), the legacy of the one-child policy, and rapid aging. India's fertility rate is also below replacement (~2.0) but its much younger age structure means it will continue to grow for another 30+ years.
