> Eight states had fewer than three ambulances covering every 1,000 square miles of land area (the Western states of Nevada, Wyoming, Montana, Utah, New Mexico, and Idaho; and the Midwestern states of North Dakota and South Dakota).

There are some good points above, but I think this one is a distraction. Many of those states on that list have low ambulance densities because they have low population densities.

Have you ever driven through Wyoming or Montana? They have less than 10 people per square mile on average. There are a couple clusters of cities and then miles of empty land.

These statistics need to be based on cities, or at least have population density taken into account. It doesn't compute to set a threshold for ambulances per square mile when the population density differs so much from state to state.
