title: Version 1

description: The Longitudinal Study of Older People in Anhui Province, China, 2001-2003 examined the physical and psychological well-being of older adults (aged 60 and above) living in rural Anhui Province, China. The original purpose of the study was to study the impact of rural-to-urban migration on the physical and psychological well-being of older adults left behind in rural villages by their adult children. This collection contains two parts; Part 1: 2001 Survey and Part 2: 2003 Follow-up Survey. Similar Questions were asked in the two surveys to assess intergenerational transfers and relations of the respondents, including social support, caregiving, emotional cohesion, remittances, grandchild care, and filial piety. Respondents were also asked about their health status (physical, emotional, and cognitive). Demographic information includes age, sex, marriage status, and education.
description: The baseline survey was conducted in April 2001 by staff and students from the Population Research Institute of Xi'an Jiaotong University in conjunction with local village officials who were trained and supervised by university personnel. Of the 1,800 individuals randomly selected for the study, 1,715 completed the survey. The completed sample included 829 men (48.8 percent) and 869 women (51.2 percent). In terms of age, 61.2 percent were 65-74 years old and 38.8 percent were 75 years and older. In October 2003, a follow-up survey was conducted with 1,368 original participants. Of those respondents who were not located, 76 had moved out of the village, and 240 died; 23 former respondents were located but refused to participate, terminated their interviews, and/or were too ill to be interviewed.

description: The sample data were collected from a sample of adults aged 60 and above living in rural townships within Chaohu, a city in the central part of Anhui province. The sample was identified using a stratified multistage method to randomly select 1,800 potential respondents. First, 12 rural townships were randomly selected from a total of 126 townships in Chaohu. Second, six administrative villages were randomly selected in each township. Third, within each selected village, all people aged 60 years and above were stratified to form two sampling frames based on age: (1) individuals aged 60-74 years, and (2) individuals aged 75 years and above, providing an intentional over-sampled population aged 75+. To guarantee that only one participant per household was interviewed, the following two measures were adopted in the sample selection procedure: If household partners were selected for each of the two age groups, then the younger partner would be dropped, and a substitute respondent would be selected randomly as a replacement for him/her; If household partners were both selected from the same age group, then the second partner chosen would be dropped, and a substitute respondent would be randomly selected as a replacement.
