Abstract: Data mining was applied to investigate the tendency of population migration. First, data of population information system was preprocessed by the analysis of attributes reduction and attributes relevance. Then the left attributes were used to construct the decision tree by the way of information gaining, and the method of combination of rules applied to decision tables was employed to refine the rules of the decision tree. Finally the basic tendency of population migration was obtained. Results indicate that, the migration rate of highly educated unmarried population and young unmarried population with little education is relative higher, and that of senile population is relative lower, while that of others is generic.
