To determine a city’s ParkScore rating, we assign points for 14 measures across five categories: acreage, investment, amenities, access, and equity.

For each of the 14 measures, points are awarded on a relative basis, based on how a city compares to the 100 largest U.S. cities. Points are assigned by breaking the data range established by our national sample into brackets, with the lowest bracket receiving the least points and the highest bracket receiving the most points.

Each city’s total points—out of a maximum of 500—are normalized to a ParkScore rating of up to 100.
