I was interested in looking at state’s where the densest 2020 census tracts are all primarily in one city or area of the state.
In playing around with it, MA, LA, NY, PA, IL, and AK all stood out as states with this sort of concentrated density.
Check out the maps below to see more!
While the number of tracts for each state in the images may seem arbitrary, if you added an additional tract, the maps would no longer be contained in their regions.
