Benefits Mapping and Analysis Program (BenMAP)

BenMAP Community Edition

BenMAP-Community Edition 1.5 (March 2019) - This is the current version of the BenMAP-CE software. 

PopGrid

BenMAP contains U.S. population data matched to a variety of commonly used air quality grids. However, users wishing to run an analysis based on an air quality grid not already defined in BenMAP may need to import a new population file matched to that grid definition. The  PopGrid program (zip file)(943 MB)  allocates the 2010 block-level U.S. Census population to a user-defined grid, creating a population file ready for importation to BenMAP.
