中国健康与养老追踪调查

中国健康与养老追踪调查（China Health and Retirement Longitudinal Survey, CHARLS）旨在收集一套代表中国45岁及以上中老年人家庭和个人的高质量微观数据，用以分析我国人口老龄化问题，推动老龄化问题的跨学科研究。CHALRS全国基线调查于2011年开展，覆盖150个县级单位，450个村级单位，约1万户家庭中的1.7万人。这些样本以后每两年追踪一次，调查结束一年后，数据将对学术界免费公开。CHARLS采用了多阶段抽样，在县/区和村居抽样阶段均采取PPS抽样方法。CHARLS首创了电子绘图软件（CHALRS-GIS）技术，用地图法制作村级抽样框。

China Health and Retirement Longitudinal Survey (CHARLS) aims to collect high-quality micro-data representative of families and individuals aged 45 years and above in China, for the purpose of analyzing China's population aging issue and promoting interdisciplinary research on aging-related problems. The national baseline survey of CHARLS was launched in 2011, covering 150 county-level units, 450 village-level units, and approximately 17,000 individuals from about 10,000 households. These samples are tracked every two years thereafter. One year after the completion of each survey, the data will be freely accessible to the academic community. CHARLS adopts a multi-stage sampling design, and the PPS sampling method is utilized in both the county/district and village/residential sampling stages. CHARLS pioneered the electronic mapping software (CHARLS-GIS) technology to develop village-level sampling frames via the mapping approach.
