【摘要】：文章对流动人口调查中抽样框的编制、重复抽选及抽选后合并、目标与抽样总体关系的复杂化等问题进行了描述和讨论。实践表明,在编制流动人口调查抽样框时,研究人员不仅需要得到相应数据库的支持,而且还应特别注意偶然性因素的影响;对规模过大或过小的抽样单位,重复抽选或抽选后合并是比较简便的方式;此外,在以"登记户籍人口"作为目标总体的调查中,受"跨界流出人口"的影响,特定地区目标总体与抽样总体的关系将表现为"一对多"的形式,数据处理时必须进行"事后加权"。为保证"事后加权"有效性,需要考虑不同省(区、市)人口流动的特点,特别是样本中"省际"和"省内"流动人口的规模。"2013年全国生育意愿调查"数据处理的过程表明,不同省(区、市)"事后加权"的分组变量及分组数量并不完全相同,具有一定的灵活性。
[Abstract]:This paper describes and discusses the compilation of sampling frame in the survey of floating population, the combination of repeated sampling and sampling, and the complication of the relationship between the target and the total sample. The practice shows that, in compiling the sampling frame of the survey, Researchers not only need to be supported by the corresponding database, but should also pay special attention to the influence of contingency factors; for large or too small sample units, it is easier to repeat or merge after sampling; in addition, In a survey with "registered household registration population" as its target population, the relationship between the overall target population and the sample population in a given area will be in the form of "one-to-many" under the influence of "cross-border outflow population". Data processing must be "ex post weighted". In order to ensure the effectiveness of "ex post weighting", the characteristics of population mobility in different provinces (regions, municipalities) need to be taken into account, In particular, the size of the "inter-provincial" and "intra-provincial" floating population in the sample. The data processing process of the "2013 National Fertility will Survey" shows that the "ex post weighted" grouping variables and the number of sub-groups in different provinces (districts, municipalities) are not exactly the same. Have certain flexibility.
