New Jersey towns of 2,500+ (468)Ahead of 56%

New Jersey towns conserve more land than most (a typical one, 11%; the U.S., 4%), so Mansfield Township’s 32% is ahead of 86% of New Jersey towns, while its trails per square mile lead 37% of them.

How sure. Graded on any three of the four inputs instead, the letter would range from A− 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.
