The line chart gives information about the changes in the proportion of birth in China and American from 1920 to 2000.
Looking from an overall perspective, it is readily apparent that both data sets varied significantly in the first half of the research years and witnesses downward trends throughout the remainder of the period. In general , the birth rates in America were higher than that of China in most years.
To be more specific, the percentage of birth in America fluctuated between just over 10% in 1920 to around 13% by 1940. Just before 1945, this figure dropped dramatically to less than 5% before a significant growth to 15% by 1950s. In the following years, the birth rates in America dipped steadily and finally reaching approximately 6% by 2000.
In terms of the birth rates in China, the figure started at 10% in the initial year and fluctuated before 1935 (between around 11% and 15%). Despite a sudden fall to 5% and no change in the 1935-1945 period, the figure of birth rates in this nation rose sharply and peaked at 20% by 1950s before fell dramatically and steadily over the following years. By 2000, the country witness the smallest rate of birth, accounting for around 3% which was nearly half of which of the USA in the same year.
