· Prevalence and risk factors of arthritis in middle-aged and older Chinese population: the China Health and Retirement Longitudinal Study

· Cohort Profile: The China Health and Retirement Longitudinal Study (CHARLS)

They will give you some context for understanding the CHARLS study, both how it was conducted ("Cohort Profile") and how data from it can be used to make conclusions ("Prevalence and risk factors of arthritis in middle-aged and older Chinese population").

Then, open up the "Codebook" (attached). You'll notice when you look between the Codebook and the rest of the Project Folder that the three datasets we've provided for this project correspond to three of the sections in the Codebook's table of contents--Health Care and Insurance, Health Status and Functioning, and Demographic Background. Because of the size of the datasets themselves, it is a good idea to use the Codebook to find the variables you like and use them to help define your questions (much easier than wading through the datasets).

For your initial post: Post a list of at least 10 variables that interest you from those available in the three sections of the Codebook for which we've provided the datasets, and describe why they interest you. Do some combinations of these variables suggest research questions?
