The line graph compares the birth rates of China and the USA and how it changes from 1920 to 2000.

Overall, the birth rates of both nations decreased over the period of 80 years.
Although the two trends were similar in terms of a general decline, the birth rate
of the USA in most years was higher than that of China.
In the 1920-1935 period, the birth rate in America fluctuated, although it always
remained above 10%. However, in the following decade, the American birth
rate fell sharply to below 5%. In the 1950s, the figure for the USA increased
significantly to exactly 15%, which was its highest point during the 80-year
period. Throughout the remainder of the period, there was a gradual decline in
the US birth rate, which fell to 7% by the year 2000.
