The baseline survey of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) was conducted in 1998, with subsequent follow-up surveys carried out in 2000, 2002, 2005, 2008 and 2011 respectively. The CLHLS baseline and follow-up surveys covered 23 out of China’s 31 provincial-level divisions, including Liaoning, Jilin, Heilongjiang, Hebei, Beijing, Tianjin, Shanxi, Shaanxi, Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Shandong, Henan, Hubei, Hunan, Guangdong, Guangxi, Sichuan, Chongqing and Hainan. The total population covered by the survey was 985 million during the 1998 baseline survey, and 1.156 billion in 2010, accounting for approximately 85% of the total national population. We randomly selected approximately half of the cities and counties from 22 survey provinces (excluding Hainan Province) as survey sites for data collection.
