Contraceptive failure was an important determinant of fertility in China in the 1980s. Based on the data from the China Two-per-Thousand Fertility Survey, this study shows that about 7% of the general fertility rate of currently married women aged 15-49 for a 12-month period is attributed to contraceptive failure, mainly due to the high failure rate associated with IUD use. A number of demographic characteristics are associated with contraceptive use, and with contraceptive failure and its outcome. Relevant socioeconomic differentials are also identified.
避孕失败是20世纪80年代中国生育水平的一个重要决定因素。基于中国千分之二生育率抽样调查的数据，本研究表明，15至49岁已婚育龄妇女12个月内的总生育率中约7%归因于避孕失败，主要原因是宫内节育器（IUD）的高失败率。一些人口特征与避孕措施的使用、避孕失败及其后果相关。研究还确定了相关的社会经济差异。
