This updated dataset reports the total number of days in which an extreme heat event was above 95th percentile between 2019-2021 at the county level. Data were obtained from the Centers for Disease Control and Prevention (CDC) Environmental Public Health Tracking Network (EPHTN).
Private School Locations
This layer displays the location of all private schools with data from the National Center for Education Statistics (NCES), 2019-20. Additional layers for private schools by religious affiliation, with pre-kindergarten programs, and by level of institution are also available.
Cancer Incidence Rates by County, 2015-2019
Layer displays cancer incidence rates (all sites) per 100,000 population by state and county. Additional map layers from this update include incidence rates for breast cancer, colon and rectum cancer, lung cancer, prostate cancer, and more.

EJ Screen Air Toxic Cancer Risk
The air toxics cancer risk indicator is the estimated lifetime inhalation cancer risk from the analyzed
carcinogens in ambient outdoor air, as provided by the 2017 Air Toxics data Update. The value of the
indicator is persons per million lifetime. The data is reported at the Census tract level. Block group level
values are assigned by repeating each parent tract level value.
Gross Domestic Product
This layer displays the 2021 Gross Domestic Product (GDP) produced within each U.S. county and the percent change in GDP from the previous year. GDP is the monetary value of all the goods and service produced within a county and is a measure of economic activity. The growth rate of GDP is the most popular indicator of overall economic health.
EJ Screen Diesel Particulate Matter
The Diesel PM indicator is the estimated concentration of Diesel PM as provided by the 2017 Air Toxics
update. The value of the indicator is in µg /m3
, and reported at the Census tract level. Block group level
values are assigned by repeating each parent tract level value.
FEMA National Risk Index, 2021
This layer displays the FEMA National Risk Index score, rating and national and state percentiles for each county and Census tract. These are measures of risks U.S. communities are exposed to for 18 natural hazards. Data was obtained from the FEMA National Risk Index (the Nov. 2021 version).
EJ Screen PM 2.5
The PM 2.5 indicator is a measure of potential exposure to inhalable particles that are 2.5 micrometers or smaller. This is measured in terms of annual average concentration in air measured in micrograms per cubic meter. PM 2.5 information included in EJScreen highlights areas across the U.S. that are not meeting the national ambient air quality standard for PM 2.5. In other words, the levels of PM 2.5 present in these areas are deemed harmful to human health. The PM 2.5 indicator in EJScreen is a measure of potential exposure but not a measure of risk. The raw PM 2.5 data is compiled by census tract which is supplied for use in the tool by EPA’s OAQPS. For air toxics risk measures (as opposed to exposure) users can turn to EJScreen’s other three indicators: cancer risk, respiratory HI, and diesel PM.
