Abstract: Estimates of the ratio and rate of induced abortion are made based on the data from annual statistics in the Ministry of Health and the National Population and Reproductive Health Survey conducted by the State Family Planning Commission in 1997, and the causes of the induced abortion are analyzed by using the 1997 survey data as well .It is found that the rate of induced abortion in urban areas was higher than that in rural areas ;the rate undertaken by conceived women who had only girls was lower than that by women who had at least one boy ;induced abortion caused by unwilling pregnancy due to the contraceptive failure was the dominant reason .However, inconsistency with the requirement of family planning was the main cause of the induced abortion in rural areas.

摘要： 利用卫生部和 1 997年全国人口与生殖健康抽样调查数据对中国妇女人工流产比和人工流产率进行了估计 ,并利用 1 997年数据对人工流产的原因进行了分析和解释。研究中发现中国城市妇女的人工流产率大大高于农村妇女 ;只有女孩的妇女再次怀孕的人工流产率低于至少有一个男孩而怀孕的妇女。由于避孕失败造成意外怀孕是中国妇女实行人工流产的首要原因 ;但是在农村 ,由于不符合计划生育规定而实行人工流产则成为主要原因。
