Pic taken from roadway.report, an interactive map of all known roadway deaths in the USA.
Fatalities resulting from motor vehicle crashes are the third largest cause of accidental deaths in the United States. On average for 2024 there were over 100 deaths per day on US roads.


#EvenThatMapEndsUpBeingAMapOfPopulation,ButMoreOfABoolean,BecausePeopleDon’tDieWhereThereAren’tPeopleAndItTakesTwoToTango
The red is higher rate of death per capita. You can die in a car by yourself in the middle of no where.

The most granular population density data in the USA can be found at the census tract level, which provides detailed demographic information for small geographic areas.
Data is not magical, however much you wish it to be.
I’ve built maps estimating how much of your lawn you are watering at at 15cm pixel resolution. Techniques to count how many cars per driveway are parked at evening hours. How much water, per hour, being used by every address in a county.
I have seen dashboards developed by collaborators who have access to near real time data regarding the physical positions of hundreds of millions of devices.
Just because its the highest resolution data that you know about, doesn’t mean its the highest resolution data which exists.
