Summary 

The Chinese Longitudinal Healthy Longevity Survey (CLHLS) collects data on the health status, lifestyle, and demographic and socioeconomic characteristics of elderly ages 65 and older in 22 provinces. The survey collected information from participants using an in-person interview, a computer-assisted self interview, and a self-enumerated questionnaire. It contains questions relating to mental state, smoking and drinking habits, health conditions, use of medical services, family, education, income, and living arrangements.

Following the 1998 baseline survey, surviving interviewees were re-interviewed, while interviewees who died were replaced by participants of the same age and sex. Family members or close friends were interviewed about deceased interviewees.

The fifth round of the survey took place in 2008-2009; while most data collection occurred in 2008, a small number of interviews took place in 2009.
