For each park, the ParkServe® team created a 10-minute walkable service area using a nationwide walkable road network dataset provided by Esri. We use the Esri Network Analyst extension to create the 10-minute walk service area. The analysis identifies physical barriers such as highways, train tracks, and rivers without bridges and chooses routes without barriers.<\/SPAN><\/P>

In order to create service areas, we created access points for each park using an auto-generation model. The model generates access points at any location where a walkable road is within a predefined distance of the park boundary. ParkServe® does incorporate the verified access points for the 100 cities in ParkScore®. <\/SPAN><\/P>

Using the 10-minute walk service areas, overall access statistics are generated for each park, place, and urban area included in the database. Access is then disaggregated by several demographic variables \u2013 race/ethnicity, age, and income. In communities with an exceptionally small number of block groups, 10-minute walk demographic calculations are not available. This information is attached for the park locations. Visit <\/SPAN>https://www.tpl.org/parkserve/downloads <\/SPAN><\/A>for field descriptions.<\/SPAN><\/P>

All calculated population statistics are based on 2018 US Census Block Group estimates provided by Esri.<\/SPAN><\/P>
