The given line graph illustrates birth rates in China and the USA and how these rates changed from 1920 to 2000.
From an overall perspective, it is obvious that the birth rates of both nations witnessed a decrease. However, there was a fluctuating upward trend in the percentages of infants in two different countries over 30-year time frame, whereas a reverse pattern could be observed in the remaining years.
Although the proportion of babies born in the US fluctuated over 10% in the 1920 – 1935 period, it plummeted considerably to below 5% in the following decade. After reaching the peak of 15%, the figure for the US showed a remarkable drop to somewhere in the vicinity of 7% by the final year.
In 1920, the percentage of birth in China was lower than that of the USA at 10%, and it increased to 15% over the same time frame with the US. However, it fell to 5% between 1940 and 1945, before reaching the highest point in the whole line graph, at 20%, in 1950. Throughout the remainder of the period, there was a gradual plunge in the Chinese birth rate to about 2% in the last year.
