Looks like the total n c1,500 was for all known projects in the dataset. The quartiles were determined from within areas with known projects.
So the Q4 range ( $133-250k median household), represents the 25% projects in the richest areas of areas that had projects in them. Hence n is 365/366 “projects” in each each group.
If there are tracts with median hh incomes way above that, but no projects, then “resistance” rate is unknown or even undefined.




Just need the bot’s waste heat to get concentrated into the kettle and I can waste two birds with one cuppa.
