How the two compare

In 2025 China has 4.12× as many people as the United States: 1.41 billion against 342 million. The difference is 1.06 billion. The United States would fit inside China 4 times over. Together they hold 21.3% of the 8.19 billion counted here.

Then and now

In 1960 the order was China ahead, 667 million to 181 million, a ratio of 3.69×. Since then China has grown 2.11× and the United States 1.89×, averaging 1.15% and 0.99% a year.

The lines never cross between 1960 and 2050: China stays ahead throughout, and the gap narrows by 2050.

Towards 2050

Projected to 2050, China reaches 1.24 billion (11.7% fewer than today) and the United States reaches 373 million (9.2% more). By then the ratio is 3.33× in favour of China.

Land and people

Land changes the picture: China has 9,388,210 km² and 150 people per km², the United States has 9,147,420 km² and 37 per km². China is 4.01× more densely settled.

Behind the totals, fertility is 1.01 in China and 1.63 in the United States; life expectancy is 78 against 78.9 years; 14.9% against 18.4% of people are 65 or older. The younger the population, the longer it keeps growing after birth rates fall.

Where the numbers come from

Figures are the World Bank's "Population estimates and projections" series, built from United Nations and national statistics. Values up to 2025 are estimates; 2026–2050 are projections that assume current fertility, mortality and migration trends continue, so they are not forecasts of events such as wars or policy changes. Territories are listed as the World Bank lists them, and a small number of places have gaps in some years.
