Data_of_HYVs

The infant mortality dataset was retrieved from China’s In-depth Fertility Sample Surveys (henceforth referred to as “fertility surveys”) of 1985 and 1987, which were conducted by the China Population Information and Research Center of the National Bureau of Statistics. In April of 1985, the first phase of the survey was implemented in Shanghai municipality and Hebei and Shaanxi provinces. The second fertility survey, following the same framework, was conducted in April of 1987 in Beijing municipality and Liaoning, Shandong, Guangdong, Guizhou, and Gansu provinces. In the last stage of random sampling, the equal probability (self-weighting) method was used to select households, from which all qualified women were interviewed by survey enumerators.

本婴儿死亡率数据集取自国家统计局中国人口信息与研究中心开展的1985年与1987年中国深入生育抽样调查（In-depth Fertility Sample Surveys，以下简称“生育调查”）。1985年4月，首轮调查在上海市、河北省及陕西省开展。遵循统一调查框架的第二次生育调查，于1987年4月在北京市、辽宁省、山东省、广东省、贵州省及甘肃省开展。在最终随机抽样阶段，本次调查采用等概率（自加权）抽样法选取调查户，由调查员对抽中户内符合条件的全部女性进行访谈。
