The provided illustration delineates the comparison of birth rates in China and the USA from the year 1920 to 2000.
Overall, the birth rates in the USA experienced a relatively stable trend, with a slight decrease from approximately 17 to 14 over the 80-year period. In contrast, China’s birth rates displayed more variability, notably spiking to over 20 in the late 1950s to early 1960s before declining to around 10 by the year 2000.
The fertility rate in China commenced at about 10 percent in 1920, increased to 15 percent by 1935, sharply dropped to 5 percent by 1945, surged to a peak of 20 percent in 1950, and concluded the century with a significant decline to around 10 percent.
Conversely, the USA witnessed fluctuating birth rates from 11 to 13 percent between 1920 and 1940, dropped to nearly 5 percent by 1945, rose gradually to approximately 15 percent by 1950, and steadily decreased to around 7 percent by the year 2000.
