This study utilizes four waves of data from 1997-2017 China Fertility Survey and analyzes the levels and trends of induced abortion since the early 21st century. Married women of reproductive age who had pregnancy history within the five years before each survey were selected as research object. The study dissected the characteristics of induced abortion in different periods, including the number and gender of children, contraceptive use, and other relevant information. The results show that the occurrence of induced abortion decreased gradually, and the risk of induced abortion was higher for those who had given birth to less children. Meanwhile, induced abortion among 2-children women increased recently. It is noteworthy that premarital induced abortions among childless women continued to increase in recent years, and the sexual and reproductive health issues of adolescents remained serious. The occurrence of induced abortions after childbirth increased for those with one or two children, showing that the unmet need for contraception after childbirth should gain more attention. In addition, sex-selective abortion has been decreasing gradually but still exists. Therefore, gender equality advocacy needs to be strengthened.
