The Chinese Longitudinal Healthy Longevity Survey (CLHLS) provides information on health status and quality of life of the elderly aged 65 and older in 22 provinces of China in the period 2002 to 2005. The study was conducted to shed light on the determinants of healthy human longevity and advanced age mortality. To this end, data were collected on a large percentage of the oldest population, including centenarian and nonagenarian; the CLHLS provides information on the health, socioeconomic characteristics, family, lifestyle, and demographic profile of this aged population. Data are provided on respondents' health conditions, daily functioning, self-perceptions of health status and quality of life, life satisfaction, mental attitude, and feelings about aging. Respondents were asked about their diet and nutrition, use of medical services, and drinking and smoking habits, including how long ago they quit either or both. They were also asked about their physical activities, reading habits, television viewing, and religious activities, and were tested for motor skills, memory, and visual functioning. In order to ascertain their current state of health, respondents were asked if they suffered from such health conditions as hypertension, diabetes, heart disease, stroke, cancer, emphysema, asthma, tuberculosis, cataracts, glaucoma, gastric or duodenal ulcer, arthritis, Parkinson's disease, bedsores, or other chronic diseases. Respondents were further queried about assistance with bathing, dressing, toileting, or feeding, and who provided help in times of illness. Other questions focused on siblings, parents, and children, the frequency of family visits, and the distance lived from each other. Demographic and background variables include age, sex, ethnicity, place of birth, marital history and status, history of childbirth, living arrangements, education, main occupation before age 60, and sources of financial support.

Sampled Universe
The elderly population aged 65 and older and their adult-children aged 35-60 in the counties and cities of 22 provinces in China during the period 2002-2005. Smallest Geographic Unit: Province
All respondents from the 9 province areas in China who agreed to participate in the study were interviewed. The 9 province areas are as follows: Beijing; Liaoning; Shanghai; Jiangsu; Zhejiang; Fujian; Shandong; Guangdong; Guangxi; During the sampling process of CLHLS in 2002, either the single surviving child, or a randomly selected surviving child of the elderly participant acted as a valid sample. More specifically, for an elderly respondent with two children, if the birth month of the elderly falls into the first half-year (January to June), the elder child was selected as a valid sample, otherwise, the younger child was selected. One year is equally divided into three parts for the elderly with three surviving children. The child whose rank by age corresponds to the sequence of the division where the parent's birth month lies was selected as a valid sample. If the parent has four or more children, one year will be equally divided into four parts: the first three parts correspond to the three elder children, and the last part corresponds to the youngest child. The adult-child samples in 2005 came from the samples of adult-child dataset in 2002 with no newly added participants.
