Population problem has always been the core of social development and a key factor restricting social development. Too fast or too slow population growth will bring certain losses to world development. Correct guidance is an important means to solve the population problem. In order to establish the mathematical model of population prediction, the total population of China, India and the world at the end of 2100 is predicted respectively, and the changing trend of population is analyzed.By establishing a generalized regression neural network model and using Matlab for programming prediction, the total population of China, India and the whole world from 1950 to 2021 are predicted respectively, and the actual population is compared to prove the feasibility of the model. Futhermore, the total population of China, India and the world in 2022-2100 is predicted, and the results are visualized.
