writing task 1: the birth rates of China and America

The given line graph compares and contrasts the data on the changes in the Chinese and American birth percentages over the 80-year period from 1920 to 2000. In overall, the rate of birth in both nations saw the significant decline but fluctuate wildly.
The most striking feature from the graph is that the figure for America was higher than that for China in most years. To specify, the birth proportion in America started at about 12% in 1920, then it has a slight fluctuation but the trend was upward to reach 13% in 1940. However, the figure plunged to just under 5% in 1945 before a remarkable increase to hit a peak of 15% in 1950. Then the American rate of birth saw a 50 - following year reduction to 7% at the end of the period.
On the other hand, the birth rate in China experienced lower values than the former. In detail, 10% was the start point of the Chinese birth proportion, and it went up and down in 20 following years between 7% before a marked reduction to reach the nadir of 5% in 5 years from 1940 to 1945. Next, the figure for China soared to peak at 20% in 1950 and declined steeply to approximately 2% in 2000.
