Mountain West metro ranking
Whitespace index (estimate): the weighted population in a metro's tracts that are short of tunnel car washes, divided by 20,000. Dense urban tracts are weighted down and income nudges demand. It ranks markets to study; it is not a count of buildable sites. Tunnels (operating only; tunnels in development are their own column and count as open in the index) and population are actual counts (tunnels verified October 2026, population Esri 2024 estimates). Rankings at 25,000 and 15,000 people per tunnel are in the map's market table.
