Hey UNC area people, I'll be giving a talk to the @unc_bioethics crew on Monday from 12-1:15 in MacNider Hall 322 on my work with @ProfCandis and @TraceeMSaunders to develop a measure of Contraception Deserts using ArcGIS. (Thanks to @douglaspmackay for the invite!)
We use an Integrated Two Step Floating Catchment Area method to combine spatial and aspatial characteristics to identify areas in NC with very poor spatial access to affordable family planning (Title X clinics), as well as areas with low spatial access and high needs population. 
We find ~25% of people in NC live in a contraception desert when we use a 15min driving distance or ~10% with a 30min driving distance. NC is actually quite well off compared to other states, according to this map of Title X provider locations nationally. nationalfamilyplanning.org/file/nationalm…
Once we have finished tinkering with our method and measure, we plan to map contraception access across more states. Title X is a federal program, so we might expect it to be allocated equitably to high needs populations within and across states.
