The obvious coupling relations between the total fertility rate and women fertility mode are shown by the analysis of the dynamics of women fertility mode using the fertility sample data of one person in every thousand. A mathematical model of Population system with percentage distribution of birth order is presented. In this model, the total fertility rate, the rate of the first birth, the rate of the second birth and the rate of third and subsequent births are chosen as control variables,...
