Chinese Health and Nutrition Survey
The China Health and Nutrition Survey (CHNS) started in the year 1989. The survey had the goal of creating a multilevel method of data collection from both individual and Chinese households. This collecting method had the aim of understanding all sorts of economic and social changes affecting nutrition and health outcomes in China. Though the survey started in 1989, it covers up to the year 2015. In this survey in-depth study and collection of new household formation and community data, was made. CHNS includes data on a total of three autonomous (Beijing, Chongqing, and Shanghai) cities and twelve provinces (Jiangsu, Liaoning, Guangxi, Guizhou, Heilongjiang, Henan, Hubei, Hunan, Shaanxi, Shandong, Yunnan, and Zhejiang). The in-depth sampling measure of this survey allowed for the construction of multiple urbanicity measures. These measures were used and studied in multiple types of research either jointly or separately.
