Abstract：Fertility intention, a variable affecting birth rate, is a key parameter of predicting reproductive behavior and birth rate. The new generation migrant workers' fertility intention is generally strong, and showing an evident preference for boys. Costs and energy demanded for raising a child and family planning policy are main factors influencing their fertility intention and behavior. To promote the effective implementation of universal two-child policy, it is advised to safeguard migrant workers' rights of bearing a second child, strengthen newly-born population surveillance and risk control.
