World GDP per capita

China and the United States are the most and 3rd most populous country in the world, respectively. China and the United States together account for about 22.7% of the total world population. China population is 4.35 times the US population, with China home to about 1.44 billion people and the United States to 331 million in 2020. The population of China will peak in 2031, but the US will not peak until 2100. China is four times denser than the US as China's population density is 153 people per square km compared to 36 of the US.

The ratio of china to the US population has increased from 3.49 in 1950 to the highest 4.69 in 1994. This ratio is expected to decline at 2.45 in 2100, as China's population growth rate is much lower than the United States.

As of period 2015-20, China's total fertility rate is 1.69 births per woman, which is lower than the US's 1.78. China's fertility rate was almost double that of the US in 1950, but it is below since 1990.

In terms of overall life expectancy, China is catching up with the United States. The margin has been reduced to 2 years, which was 25 years in 1950. The United States came 47th globally, with 78.81 years, while China is at 72th with 76.62 years. China (38.42 years) has overtaken the United States (38.31 years) in terms of median age.

The US has a higher old population share as 16.6% of the US population has age above 65 years, compared to 12% of China. The United States has more people ages above 95 years.
