For day 12 of #30DayMapChallenge, the theme is movement. Here& #39;s an updated map of dollar store density from 2008-2019 at county level using SNAP authorized retailers (>95% of locations).

And here& #39;s a similar map for Aldi.

Last one for now (and much more geographically narrow): Wawa

All maps made in #rstats using tmap and the really helpful gifski tool for gif creation.

I& #39;ve now added the script for the Aldi and Wawa maps to the SNAP retailer Github repo. I pulled county and state boundaries from @kyle_e_walker& #39;s awesome tidycensus package. https://github.com/jshannon75/snap_retailers/blob/master/scripts/chain_year_analysis_2019_11_10.R">https://github.com/jshannon7...
