OpenAddresses / population

Justin Meyers did an awesome treatment of OpenAddresses data. He put all the points in QGIS, then binned them by county, then put the shapefile in a repo. Nice! I wanted to see what the data looked like normalized by population, so I did two treatments. One is kinda sorta logarithmic, the other is a simple linear scale capped at 2 addresses / person.

Linear, capped at 2

I’m not quite sure what this visualization really shows. I was hoping it’d be a proxy for data coverage; like naively I expected there’d be one address per person, more or less. But that’s clearly not what I’m seeing here. The Montana outlier is particularly baffling, there’s 10 addresses / person in many counties.
