3、eveal the relationship between them, the better for the population statistics service. Firstly, by means of the parity fertility rate of fertility ( weights obtained by information entropy decision-making method to obtain weights ), weight after fertility as womens fertility rate, then get the total

4、 population data and the number of primary school enrollment in the Ministry of education to correct the population from the population of China Statistical Yearbook, to minimize errors due to under-reporting false negatives bring. Followed by the establishment of the total population and fertility rate model, and the model using two steps ahead of the data to obtain the fitting function. keywords： The total population； data weighted； fertility rate； function fitting.
