In this figure we can see the sex ratios among children of age 0-14 in three countries (China, India, and United States) vs. corresponding total populations. What I tried to find out is how China’s national population control policy affects the sex ratio. We can see that from 1950, the population of China and India increase dramatically. However, the sex ratio for India does not increase while that for China reaches 120 (120 boys vs 100 girls). My hypothesis is that this is due to the national policy and modern technologies allow people to select the gender of their babies. This high sex ratio of modern china may be a dangerous sign for the future of China.
