I am planning a project to look at the spatial-temporal spread of income over time. Hence, I am looking for data on household or individual level income information for India, China, and East/West African nations--with spatial coordinates or GIS info. This is really a comparative study of development. So I was wondering if there are any good open sources of data on income for these nations. I am i This type of information is pretty hard to come by, so I thought that perhaps there might be some decent proxy variables for income, such as consumption information, or living standards, even child mortality. I would like to stick with the original variable of income if I could and explore alternative proxies if I have to. I can build a web scrapper if I have to and attack the problem that way, but I was not sure of was sources of information exist and what website I would scrape if I could.
Also note I am hoping to stay away from highly aggregated information because I am worried about losing too much information in the averaging process.
