The mid-term review of large data project begins running. This review is authorized by the NSFC and conducted by the Expert Supervising Committee of Large Data Projects appointed by the NSFC. Two online surveys will be conducted to evaluate these two data projects.

Since 2012, the National Natural Science Foundation of China (NSFC) has supported the China Health And Retirement Longitudinal Study (CHARLS) and Chinese Household Income Project (CHIP). Many researchers have used CHARLS or CHIP for their own research. The purpose of the mid-term review is to help improve CHARLS and CHIP.
