Map 1: LIDAC Disadvantaged Communities by Block Group
The LIDAC (Lower Income and Disadvantaged Community) by Block Group map combines CEJST disadvantaged communities and EJ Screen communities above the 90th percentile in any of state-level supplemental indexes or national-level supplemental indexes. The geographic units are 2020 Census block groups. The data and documentation are available from the EPA here.
Map 2: Counties with Over 80% Population Living in Disadvantaged Communities
The LIDAC (Lower Income and Disadvantaged Community) Population by County map combines CEJST disadvantaged communities and EJ Screen communities above the 90th percentile in any of state-level supplemental indexes or national-level supplemental indexes. Data for each county has been aggregated for all block groups in the county and the map shows all counties with over 80% of the population living in LIDAC communities (block groups). The data and documentation are available from the EPA here.
Map 3: LIDAC Disadvantaged Population by Census Tract
The LIDAC (Lower Income and Disadvantaged Community) Population by Census Tract map combines CEJST disadvantaged communities and EJ Screen communities above the 90th percentile in any of state-level supplemental indexes or national-level supplemental indexes. The geographic units are 2020 census tracts. Data for each tract has been aggregated for all block groups in the tract and the map displays the percentage of disadvantaged population in each tract. The data and documentation are available from the EPA here.
Map 4: LIDAC Disadvantaged Population by County
The LIDAC (Lower Income and Disadvantaged Community) Population by County map combines CEJST disadvantaged communities and EJ Screen communities above the 90th percentile in any of state-level supplemental indexes or national-level supplemental indexes. Data for each county has been aggregated for all block groups in the county and the map displays the percentage of disadvantaged population in each county. The data and documentation are available from the EPA here.
Map 5: CEJST Disadvantaged Communities with Eight Classes of Burdens
The “Disadvantaged” layer is colored when the tract is designated by CEJST as disadvantaged. The other eight layers are for specific classes of burdens. If a tract is disadvantaged for one or more of the eight classes of burdens, it receives an overall designation as disadvantaged. The geographic units for CEJST 1.0 are 2010 census tracts. Data for the map was generated by the Climate and Economic Justice Screening Tool (https://screeningtool.geoplatform.gov).
Map 6: CEJST Quartile Map(s) of Air Pollution Measures
Each of the four colors on the air pollution maps represents 25% (one quartile) of the Georgia census tracts. PM 2.5 is fine particulate matter that results from burning fossil fuels. Diesel particulate is generated by trucks and other vehicles burning diesel fuel. The Traffic Proximity Index is the result of evaluating each tract’s distance to traffic and the volume of traffic nearby. Data for these maps was generated by the Climate and Economic Justice Screening Tool (https://screeningtool.geoplatform.gov).
Map 7: EJScreen Map of State and National Supplemental Indices
This map shows Georgia communities (block groups) that are in the highest 10% of communities for any one of 26 supplemental indices related to 13 environmental indicators. There are 26 indices because a community can be in the highest 10% of communities at either the national or the state levels. Click on any community to see its values for all 26 indices. The 13 environmental indicators are:
-
pm25: Particulate Matter 2.5; Annual average PM2.5 levels in air
ozone : Ozone; Average of the annual top ten daily maximum 8-hour ozone concentrations in air
dslpm : Diesel particulate matter; Diesel particulate matter level in air
cancer : Air toxics cancer risk; Lifetime cancer risk from inhalation of air toxics
resp : Air toxics respiratory HI; Ratio of exposure concentration to health-based reference concentration
rsei_air: Toxic Releases to Air; RSEI modeled toxicity-weighted concentrations in air of TRI listed chemicals.
ptraf : Traffic proximity; Count of vehicles (AADT, avg. annual daily traffic) at major roads within 500 meters, divided by distance in meters (not km)
ldpnt : Lead paint; Percent of housing units built pre-1960, as indicator of potential lead paint exposure
pnpl : Superfund Proximity; Count of proposed or listed NPL – also known as superfund – sites within 5 km (or nearest one beyond 5 km), each divided by distance in kilometers
prmp : RMP Facility Proximity; Count of RMP (potential chemical accident management plan) facilities within 5 km (or nearest one beyond 5 km), each divided by distance in kilometers
ptsdf : Hazardous waste proximity; Count of hazardous waste facilities (TSDFs and LQGs) within 5 km (or nearest beyond 5 km), each divided by distance in kilometers
ust : Underground storage tanks; Count of LUSTs (multiplied by a factor of 7.7) and the number of USTs within a 1,500-foot buffered block group
pwdis: Wastewater discharge; RSEI modeled toxic concentrations at stream segments within 500 meters, divided by distance in kilometers (km)
