What caused this decrease in population (you will need to research why this population decrease happened)? [2 points] In 1958, Chinas population was at a peak of 13.79 million and then had a dramatic drop from year 1958 to 1961 where the population in China dropped to 1.09 million. Chinas population dropped a complete 12.70 million within 3 years. The decrease was due to the Great Chinese Famine which was during the Great Leap Forward. Its purpose was to quickly change China from an agrarian society into an industrialized socialist society. 3.
