Population is a source of a nations’ strength and national security, but some overpopulated countries in Asia are trying to lower their population growth, even implementing population control policies. This paper conducts a comparative study of China and India to explore the effectiveness of their population control policies, and its findings suggest that education can be one of the strongest methods to curb the population explosion, reducing its side effects by giving Kerala case. This study suggests that further attention must be given to more cases in China and India related to the correlation between the level of education and population growth. Also, the case of Kerala will be needed to be researched more in-depth and yield more concrete recommendations to facilitate an added value to this field.
