Outdoors grade

How much outdoors does Ketchum have?

On conserved land, trails, park land and how close residents live to a park, Ketchum is ahead of 72% of U.S. towns, #13 of 59 in Idaho. Trail miles hold the grade up; park acres per resident pull it down.

B+
OutdoorsA character grade: shown, never part of Ketchum’s overall grade.
All U.S. towns we grade (21,298)Ahead of 72%
LessMore
Idaho towns of 2,500+ (59)Ahead of 79%

Few Idaho towns conserve much land (a typical one, 2%; the U.S., 4%), so Ketchum’s 10% is ahead of 97% of Idaho towns, while its trails per square mile lead 74% of them.

How sure. Graded on any three of the four inputs instead, the letter would range from B to A−. Trails and many small parks come from OpenStreetMap, mapped by volunteers, so coverage varies from town to town; the half mile is a straight line from each census block, so a river or highway in the way isn’t counted against it.
