To explore the second child bearing willingness of migrants after the policy of “comprehensive two children” and analyze the influencing factors.

Based on the Hubei provincial data of 2016 National Migrant Population Dynamic Monitoring Survey, the second child bearing willingness of 15 to 49 years old migrants who have had one child already were surveyed and the influencing factors through multinomial logistic regression model were analyzed.

About 20.10% of the migrant population had a clear family planning of the second child. Gender, age, the nature of household registration, educational level, employment status, gender of the first child, income, medical insurance, reason for this current migration, cumulative floating time, long-term residence planning in inflow place affected the second child bearing willingness on migrant population.

The migrant population has a low fertility willingness of the second child, and it’s affected by many factors. It is suggested that various measures should be taken to enhance the migrant populations’ desire to have a second child by strengthening the propaganda of the universal two-child policy, reducing the economic pressure, and improving the related resources and facilities for bearing and raising of the second child.
