Tools for EJSCREEN, US EPA's Environmental Justice (EJ) Screening and Mapping Tool

Description

This R package provides tools related to environmental justice (EJ) analysis, specifically related to the United States Environmental Protection Agency (EPA) screening and mapping/GIS tool called EJSCREEN. See http://www.epa.gov/ejscreen This package facilitates development of the EJSCREEN dataset, based on user-provided environmental indicators. The resulting dataset is a data.frame that contains data on demographics (e.g., percent of residents who are low-income) and user-provided local environmental indicators (e.g., an air quality index), and calculated indicators called EJ Indexes, which combine environmental and demographic indicators. The dataset also provides each key indicator as a national population-percentile that represents what percentage of the US population have equal or lower raw values for the given indicator. The dataset has one row per spatial location (e.g., Census block group).

Details

Key datasets are [bg22], [ejscreenformulas], and the percentile lookup tables

Key functions include

  • ejscreen.download To download the raw data from the FTP site.

  • ejscreen.create To create a dataset of demographic indicators, EJ indexes, etc. starting with your own environmental indicators and taking demographic raw data from the American Community Survey (ACS).

  • ejscreen.lookuptables To create the file that shows percentiles for each indicator

  • Various functions from the ejanalysis package are also relevant.
