The graph demonstrated some striking similarities between the Chinese and the US birth rates from 1920 to 2000.
The birth rates in China rose from 10% in 1920 to 15% in 1935. Later, the figure plunged to a low of 5% in the 1940s and was followed by an exponential growth to the peak of 20% in 1950. Next, the fertility rate dropped sharply to 8% in the following five years. Finally, the figure declined gradually to 3% during the latter half of the century.
Meanwhile, the US had similar birth rate of 12% to that of China in 1920. The figure fluctuated in between 12% and 14% during 1920s and 1930s until it hit a low of 4% in 1945. Five years later, the birth rate reached a peak at 15% in 1950 but it made a steady fall to the final figure of around 7% in 2000.
Overall, both countries experienced considerable fluctuations in the similar period with some lows during the 1940s and some highs during the 1930s.
