Based on the analysis and comparison of nationwide statistical data regarding divorce rate and young divorce population，this article has the following findings：since reform and opening up，the national divorce rate has generally increased to a great extent；under this context，the divorce risk among contemporary Chinese youth has somewhat increased on the whole. However，according to the proportion of different age among divorce population，the young people are not the main force of divorce population actually. On the contrary，the proportion of young divorce population in the whole divorce population has somewhat decreased to some extent. During the past twenty years，the proportion of young divorce population in rural areas has increased significantly；while in urban areas，the proportion of young divorce population has decreased due to the constant delay of age of first marriage. Regarding the influencing factors，this article tries to combine the survey data from “2019 National Youth’s View of Marriage and Love” together，and analyze the reason for constant increase in divorce rate from five aspects，namely cultural idea，population mobility，social policy，media communication and change of gender roles. Regarding the countermeasures and suggestions，this article emphatically discusses how law system and policy for public service should protect marriage system and improve marriage stability；meanwhile，this article also proposes some concrete suggestions on how to strengthen marriage education and service towards young people.
