EJAM.RdEJAM provides a way to run hundreds or thousands of location-specific reports all at once, very quickly. It is also an R package, with functions and data for very fast analysis of areas defined by proximity to points like regulated facilities, areas defined as shapefiles/polygons, or areas specified as Census units (e.g., Counties).
What is EJAM and How to do Analysis with the EJAM R Package
EJAM package documentation provides an overview of EJAM, a complete reference document on all functions, and articles (vignettes) introducing key functions and how to use them.
Data Sources – Residential Population and Environmental Indicators
Documentation provides information about the sources, definitions, and vintage of the residential population and environmental data and indicators used by EJAM.
Each year, EJAM should updated to use newer residential population and environmental data, and some indicators may be added, dropped, or revised during those updates. For details on these updates and changes to datasets and indicators, please note the information about updates and changes: Data Change Log. Residential population data are from the American Community Survey 5-year summary file data that are updated by the United States Census Bureau annually and then used in EJAM.
