NOTE: The 2017 version of this documentation will be replaced with an updated version in early 2020. EJSCREEN is updated annually, so the vintage of the dataset and data sources has changed since the 2017 version of the technical documentation. For example, the 2019 version of EJSCREEN uses the 2013-2017 ACS 5-year summary file data, but the 2017 documentation still refers to the 2011-2015 ACS data, which had been used in the 2017 version of EJSCREEN. Other than references to the vintage of the data and sources, and updates to the water and TSDF indicators, the information in the 2017 version of the technical documentation remains applicable to the 2019 version of EJSCREEN. Updated information about those two changed indicators and updated data source vintages can be found on the latest EJSCREEN webpage about environmental indicators, at https://19january2021snapshot.epa.gov/ejscreen/overview-environmental-indicators-ejscreenYou may need a PDF reader to view some of the files on this page.
