Missouri towns of 2,500+ (247)Ahead of 6%
Few Missouri towns conserve much land (a typical one, 2%; the U.S., 4%), so Mehlville’s 1% is ahead of 27% of Missouri towns, while its trails per square mile lead 6% of them.
NoteFew parks or trails are mapped in Mehlville. OpenStreetMap is mapped by volunteers and coverage varies from town to town, so a town with unmapped parks scores low on them.
How sure. Graded on any three of the four inputs instead, the letter would still be D. 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.
