The AWP Social Atlas dataset was developed by students enrolled in Dr. Jerry Shannon's Community GIS class in Spring of 2016 and 2017. It includes data from a variety of sources, including the U.S. Census, agencies in the Athens-Clarke County government, and a Health Needs Assessment conducted in 2015. Students used a technique called aerial interpolation to change data from estimates for census tracts to ones for specific school attendance zones, which were larger than tracts.
The full spreadsheet of the data and the source of specific variables can be found here.
