Abstract: This article introduces the process of the 2017 China Fertility Survey from the perspective of data quality control.The individual questionnaire includes four sections:fertility desire,fertility behavior,childbearing and its services,and the determinants of fertility behavior.The sampling method is the three-stage probabilities proportional to size (PPS).The survey is applied with Computer Assisted Personal Interviewing (CAPI),which plays an important role in the quality control of questionnaire designning,interviewers training,last-stage sampling,interviewing,and questionnaire review.After the on-site survey,the survey results are compared with the relevant registration data in the population and family planning data repository,and the inconsistent data are fed back to the local supervisors for verification.In order to correct the potential sample structure bias caused by some defects in the sampling frame,ex post facto weighting is applied based on relevant data.In the future,the sampling frame may still be subject to distortions because of population migration.Regarding these issues,this paper makes suggestions for improvement.
