This layer displays the percentage of Medicare beneficiaries with opioid use disorder in the latest report year (2020).
EJ Screen Lead Paint Exposure
The lead paint indicator is the percentage of occupied housing units built before 1960, calculated from
the U.S. Census Bureau’s ACS 5-year summary estimates on age of housing stock. EJScreen uses age of
housing stock as a surrogate for potential lead exposure as regulations banning lead-based residential
paint in 1978 led to the reduction and finally an end to the use of such paint in housing. The percentage
of older housing units is a proxy for potential exposure to lead paint and lead-containing dust that
accumulates indoors, in homes, or in other buildings where lead paint was used. EJScreen uses housing
units built before 1960.
Influenza Vaccination by County, Adult (2021)
This layer displays immunization rates for seasonal influenza among adults aged 18 and older. Data are from the Centers for Disease Control and Prevention (CDC) FluVaxView data portal. The county-level estimates within FluVaxView are derived from responses to the 2021 BRFSS.
EJ Screen Air Toxic Respiratory Risk
The air toxics respiratory HI indicator is the respiratory HI from the analyzed carcinogens in ambient
outdoor air, as provided by the 2017 Air Toxics Data Update. The data is reported at the Census tract
level. Block group level values are assigned by repeating each parent tract level value.
Influenza Vaccination by Vaccination Setting (Non-Medical Setting)
This layer displays the proportion of the county population immunized for influenza aged 18 years or older who have received the vaccination in a non-medical setting. Data are from the Centers for Disease Control and Prevention (CDC) FluVaxView data portal. The county-level estimates within FluVaxView are derived from responses to the 2021 BRFSS.
EJ Screen Superfund Proximity
The Superfund proximity indicator is reflective of the total count of sites proposed and listed (final) on
the National Priorities List (NPL) in each block group within 5 km of the average resident in a block
group, divided by distance, calculated as the population-weighted average of blocks in each block group.
Air Quality – Ozone Levels (O3) by Census Tract, 2019
This layer displays the daily average concentration of ozone and the percentage of days with concentrations of ozone above the National Ambient Air Quality Standard (NAAQS) of 0.075 parts per million in 2019.
Cancer Incidence Rates by County, 2016-2020
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 Hazardous Waste Proximity
The hazardous waste proximity indicator is reflective of the total count of hazardous waste facilities in
each block group within 5 km of the average resident in a block group, divided by distance, calculated as
the population-weighted average of blocks in each block group. Hazardous waste facilities are defined as
Resource Conservation and Recovery Act (RCRA) handlers that are either operating TSDFs from RCRA or
reporting LQGs from the 2019 BR.
Uninsured Population by County
Layer displays information about the insurance status of the population age 0-64. The data are from the 2021 Small Area Health Insurance Estimates, released by the US Census Bureau in August, 2023.
