It is one of the most significant demographic milestones of our lifetime, and it happened with surprisingly little fanfare: India is now the most populous country on Earth. The 2024 population ranking puts India at 1,428 million people, edging past China's 1,411 million.

A 17-million-person lead that will keep growing

The current gap — about 17 million people — may look small next to totals of 1.4 billion. But the two countries are moving in opposite directions. China's population has already begun shrinking, the result of decades of below-replacement birth rates and the long shadow of the one-child policy. India's population is still growing and is projected to keep doing so into the 2060s. This is not a photo finish; it is a permanent changing of the guard.

The scale of the top two

India and China together hold about 2.84 billion people — more than the next twenty countries combined would manage. The United States, third on the list, has 340 million people: less than a quarter of either Asian giant. Behind it come Indonesia (278M), Pakistan (245M), Nigeria (224M), Brazil (216M) and Bangladesh (173M).

Nigeria is the name to remember

Sixth-placed Nigeria is the fastest riser in this group. UN projections have it passing the United States to become the world's third most populous country around mid-century. Combined with strong growth across Africa, the continent's share of the global population is set to rise dramatically — with everything that implies for markets, migration and geopolitics.

Population is not the same as connectivity

Interestingly, the population ranking does not map neatly onto the digital world. China still has far more internet users (1,092 million) than India (900 million), because a larger share of its population is online. India's connectivity gap is also its growth story: hundreds of millions of future internet users are already there, waiting for infrastructure to reach them.

The takeaway

The 2024 numbers mark the end of an era that lasted for centuries. China's population peak and India's continued rise will reshape labor markets, consumer demand and global politics for the rest of this century — and Nigeria's climb suggests the next demographic story is already underway.
