This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets). The purpose of this dataset is to show block groups within the EnviroAtlas community boundary that have schools with little green space within their proximity. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation. completed EnviroAtlas Coordinator US Environmental Protection Agency, Research Triangle Park ORD/NERL/EnviroAtlas 000-000-0000 109 TW Alexander Dr. Research Triangle Park NC 27711 EnviroAtlas@epa.gov pointOfContact asNeeded Ecosystem Environment theme EPA GIS Keyword Thesaurus Census Block Groups Communities Demographics Ecosystem Services EnviroAtlas Environment Environmental Atlas Green Space Human Well-being theme EnviroAtlas Arizona Phoenix, AZ place None https://edg.epa.gov/EPA_Data_License.htm otherRestrictions Use Constraints: None.

This dataset describes the number of schools in each block group and the number of those schools with less than or equal to 25% greenspace within 100 meters. The processing steps were completed using Python scripts. A comprehensive list of metric creation steps is included in the Processing Steps.
