      @wellerstein (Some of the green areas are errors, not actually representative of density. Still tweaking.)

      @micahstubbs This is the Oak Ridge LandScan database. It's not open data, unfortunately. It is what powers the NUKEMAP's casualty figures.

          @micahstubbs The population data is something you have to buy a license for. (Not very cheap.) Once you have the data, you can play with it.
