The Trust for Public Land’s ParkScore index is the most intensive system ever developed for measuring how well the 100 largest cities in America are fulfilling the community need for parks and recreation. They use advanced mapping technology (GIS) to gather comprehensive data to help guide park development. One of the primary factors that is weighed is how many people are able to reach a park within a 10-minute walk. Parks are vital to community health, happiness, and wellbeing. Nearby opportunities for exercise and exposure to nature are shown to boost physical activity, reduce crime, energize local economies, and unite neighborhoods. This infographic identifies which major U.S. cities score the highest and which cities excel or are lacking in a number of different categories.
