Based on the dynamic monitoring data of floating population of National Health and Family Planning Commission in 2016 and taking the floating population of Beijing，Tianjin and Hebei as the sample，this paper focuses on the health education，health security and health self-assessment of the floating population in Beijing-Tianjin-Hebei area. The results are as follows：（1）In the aspect of health education，the health education of floating population in Beijing-Tianjin-Hebei area is generally popular，but the content of education is not comprehensive enough and the contents of mental disorder prevention，occupational disease prevention and so on are less. Different age groups of floating population choose different ways to acquire health knowledge. The health knowledge acquisition of floating population is positively related to education level and occupational status.（2）In the aspect of health security，the local coverage rate of floating population in Beijing-Tianjin-Hebei area is relatively low and there is a big difference among the three places，the highest in Beijing area and the lowest in Hebei. The floating population mainly participated in the new rural cooperative medical insurance and urban workers’ medical insurance. The floating population participating in different types of insurance had different demographic characteristics.（3）In the aspect of health self-assessment，the health self-assessment of the floating population in Beijing，Tianjin and Hebei is generally good and the education level，occupation status and floating time will affect the health self-assessment of the floating population. On the whole，in the Beijing-Tianjin-Hebei area，the floating population groups with a higher degree of socioeconomic integration may have more health knowledge and more health protection，thus maintaining good health status. In this respect，Beijing area has more obvious advantages.
