Description: The ParkServe database maintains an inventory of parks for every urban area in the U.S., including Puerto Rico. This includes all incorporated and Census-designated places that lie within any of the country’s 3,000+ census-designated urban areas. This totals to over 15,000 cities, towns, or villages included in the database, which represents about 75% of the U.S. population. We calculate a 10-minute walk service area for each park in the database by creating a half-mile 'walkable' service area from each of the park's public access points. This service area is created using Esri’s Street Map Premium network dataset, which allows us to account for physical barriers such as highways, train tracks, or rivers without bridges.Using these 10-minute walk service areas, we generate overall access statistics for each urban area included in the database (e.g. number of people within a 10-minute walk of a park). This statistic is further disaggregated for three demographic variables – race/ethnicity, age, and income. In communities with an exceptionally small number of block groups, 10-minute walk demographic calculations are not available. All calculated population statistics are based on US Census Block Group estimates provided by Esri.
