ECHO Facility Demographic Download Summary
ECHO incorporates data from the U.S. Census, American Community Survey (ACS), and the 2010 Census Block Groups Data (CBG) database to derive information about demographic characteristics surrounding each facility's location. On this page:
Demographics Description
The demographic profile of the surrounding area is provided for each facility with coordinates on the ECHO Detailed Facility Report. This data download compiles the demographic profile information for all facilities into one dataset.
The sources of demographic data are the 2010 U.S. Census and American Community Survey (ACS) 2017 - 2021 five-year summary file, which the U.S. Census Bureau compiles yearly. The source of each data element is indicated below.

ECHO Demographics Data Element Definitions
Definitions are listed in the order presented in the data table.
REGISTRY_ID
The Facility Registry Service (FRS) ID of the facility. FRS uniquely identifies a facility by assigning an identification number (FRS ID), and uses this FRS ID to link together all regulatory program database records (such as permit IDs and facility IDs that facilities uses in reporting to the EPA).
RADIUS_OF_AREA
The number of miles, in any direction, from the center point of the facility that is included in the demographic profile. ECHO derives demographic information for the area within 1, 3, and 5 mile radii of the facility's coordinates. The radius is measured from the best available latitude/longitude coordinate of the facility or permit holder.
Note: The Census data records distance in kilometers whereas the Integrated Data for Enforcement Analysis (IDEA) database has chosen to display distances in miles. As a result, IDEA has created derived fields in the flattened CBG files which convert Census values to reflect miles instead of kilometers. To make this conversion, distances in kilometers have been divided by the number 1.6 (the number of kilometers in a mile). In the case of an area (given in square kilometers), the number is divided by 2.59, the square of 1.6.
TOTAL_AREA
The total area of a census block group within a given radius.
LAND_AREA
The total area that is land (not water). This is calculated using the sum of the land areas of the census block groups within the given radius.
WATER_AREA
The total area that is water (not land). This is calculated using the sum of the water areas of the census block groups within the given radius.
ACS_POPULATION
The total number of persons that reside in the profiled area, based on the 2017-2021 ACS 5-Year Summary.
