From approximately 10% in 1920, the birth rates in China fluctuated and reached 15% in 1935, then decreased rapidly to 5% in the 1940s. The next 5 years saw a increase in the birth rates, to the peek of 20% in 1950, followed by a period of decline.
The birth rates in the USA also fluctuated in the same time, from around 11% to 13% between 1920 to 1935, before went down quickly from 1935 and dropped to only 5% in 1945. Over the following 5 years, the rates raise slowly and got the highest at 1950, which was 15%. The latter half of the century, the fertility rates in the USA reduced to roughly 7% in 2000.
