AP Outcomes are often correlated to measures of socioeconomic factors. It would be interesting to compare AP outcomes to factors that are less dependent on income for example, nearby universities or potentially military bases. Shannon has been able to find state by state rates of exams over 3 on the AP website and the college board is inviting requests, so it is potentially possible to get information more broken down. Unversities as defined by R1/R2/etc is not difficult to find nor are military bases. Please message, Shannon, on slack if you have questions.
