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.
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.
EJ Screen RMP Facility Proximity
The RMP facility proximity is reflective of the total count of RMP 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
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.
EJ Screen Underground Storage Tanks
The UST indicator quantifies the relative risk of being affected by a LUST for a block group. The indicator
is derived by the weighted sum of active LUSTs and sum of active and temporarily out of service USTs
within a certain distance from a block group.

Affordable Connectivity Program Subscribers
This layer displays the total number of household subscribers in the Affordable Connectivity Program by data month. The Affordable Connectivity Program is an FCC benefit program that helps ensure that households can afford the broadband they need for work, school, healthcare and more.
Commuting Distances
This layer displays the mean distance traveled by commuters, based on the centroids of the census blocks in which the reside and work. The mean was calculated excluding those records where the distance traveled was over 125 miles one-way. Additional data layers are available which show the proportion of commuters with a short (< 5 miles), moderate (5 – 25 miles), long (25 – 75 miles), or very long (75 – 125 miles) commute.
