Abstract

Connecticut EJ communities maps is a collection of csv files downloaded from Connecticut Department of Energy and Environmental Protection's ArcGIS website. The csv files contain data that was used to generate three main maps: Connecticut 2021 EJ communities, Connecticut: Environmental Justice Affecting Facilities, and Connecticut Demographics and Affecting Facilities. A link to each map is available under the Links section below.

The Environmental Justice Communities Map (“EJ Communities Map”) describes areas of San Francisco that have higher pollution and are predominately low-income. This map is based on CalEnviroScreen, a tool created by CalEPA & OEHHA that maps California communities that are most affected by pollution and other health risks. This EJ Communities Map includes additional local data on pollution and demographics, and was refined during the community engagement process based on public feedback. “EJ Communities” are defined as the areas facing the top one-third of cumulative environmental and socioeconomic burdens across the City. The EJ Communities include areas of Bayview Hunters Point, Chinatown, Excelsior, Japantown, Mission, Ocean View-Merced Heights-Ingleside, Outer Mission, Potrero Hill, SoMa, Tenderloin, Treasure Island, Visitacion Valley, and Western Addition.

"EJ Communities” are defined as the areas facing the top one-third of cumulative environmental and socioeconomic burdens across the City, with scores 21-30.

The table EJ Block Groups is part of the dataset Connecticut EJ Communities Maps, available at https://redivis.com/datasets/ck4g-d60ynh7dt. It contains 318 rows across 6 variables.

description: These data are from EJSCREEN, an environmental justice (EJ) screening and mapping tool that provides EPA with a nationally consistent dataset and methodology for calculating "EJ indexes," which can be used for highlighting places that may be candidates for further review, analysis, or outreach as the agency develops programs, policies and other activities. The tool provides both summary and detailed information at the Census block group level or a user-defined area for both demographic and environmental indicators. The summary information is in the form of EJ Indexes which combine demographic information with a single environmental indicator (such as proximity to traffic) that can help identify communities living in areas with greater potential for environmental and health impacts. The tool also provides additional detailed demographic and environmental information to supplement screening analyses. EJSCREEN displays this information in color-coded maps, bar charts, and standard reports. Users should keep in mind that screening tools are subject to substantial uncertainty in their demographic and environmental data, particularly when looking at small geographic areas, such as Census block groups. Data on the full range of environmental impacts and demographic factors in any given location are almost certainly not available directly through this tool, and its initial results should be supplemented with additional information and local knowledge before making any judgments about potential areas of EJ concern.; abstract: These data are from EJSCREEN, an environmental justice (EJ) screening and mapping tool that provides EPA with a nationally consistent dataset and methodology for calculating "EJ indexes," which can be used for highlighting places that may be candidates for further review, analysis, or outreach as the agency develops programs, policies and other activities.

Environmental Justice Block Groups 2022 was created from Connecticut block group boundary data located in the Census Bureau's 2020 TIGER/Line Shapefiles. The poverty data used to determine which block groups qualified as EJ communities (see CT State statute 22a-20a) was based on the Census Bureau's 2020 ACS 5-year estimate. This poverty data was joined with the block group boundaries in ArcPro. Block groups in which the percent of the population below 200% of the federal poverty level was greater than or equal to 30.0 were selected and the resulting selection was exported as a new shapefile. The block groups were then clipped so that only those block groups outside of distressed municipalities were displayed. Maintenance – This layer will be updated annually and will coincide with the annual distressed municipalities update (around August/September). The latest ACS 5-year estimate data should be used to update this layer. Environmental Justice Distressed Municipalities 2020 was created from Connecticut town boundary data located in the Census Bureau's 2020 TIGER/Line Shapefiles (County Subdivisions).

From this shapefile, "select by attribute" was used to select the distressed municipalities by town name (note: the list of 2022 distressed municipalities was provided by the CT Department of Economic and Community Development). The selection was then exported a new shapefile. The “Union” tool was used to unite the new shapefile with tribal lands (American Indian Area Geography) boundary data from the 2020 TIGER/Line files. In the resulting layer, the tribal lands were deleted so only the distressed municipalities remained. Maintenance – This layer will be updated annually when the DECD produces its new list of distressed municipalities (around August/September).

Note: A distressed municipality, as designated by the Connecticut Department of Economic and Community Development, includes municipalities that no longer meet the threshold requirements but are still in a 5-year grace period. (See definition at CGS Sec. 32-9p(b).) Fitting into that grace period, eight towns continue to be eligible for distressed municipality benefits because they dropped off the list within the last five years. Those are Enfield, Killingly, Naugatuck, Plymouth, New Haven, Preston, Stratford, and Voluntown.

For use in determining project location's proximity to schools and EJ Index Ozone areas for the Air Quality Small Grant Program. Data layers are updated every year in anticipation of a new Call for Projects.

Current, March 2024 revision, IMPO Environmental Justice Areas based on 2020 Census Block Groups selected by the 2020 MPA boundary. https://www.indympo.org/maps-and-data/maps/demographics-environmental-justice “Environmental Justice (EJ) refers to the process of evaluating and analyzing the planning process in reference to the most disadvantaged populations. Environmental Justice populations are identified by the federal government as low-income and minority populations. As part of our planning process, we evaluate the impact our projects have on these populations." “For each census block group within the Metropolitan Planning Area, 2022 ACS Five-Year data was used to compare the rate* of a specific EJ population within the block group to the rate of that population in the overall region. The map identifies which EJ populations for each block group exceed the regional rate for that population. Because the IMPO is federally mandated to consider the benefits to and burdens of minoritized people and low-income households, those categories are specifically highlighted in the map and considered to be Environmental Justice Areas of Attention (EJAs). The map also identifies five other EJ populations including people with limited English proficiency, low educational attainment, households with no automobiles available, people over the age of 65, and households with disabilities. These groups are not federally mandated for consideration but are indicated here by the IMPO because they can also be disproportionately impacted by transportation projects."

Environmental Justice 2024 Set is comprised of two layers: Environmental Justice Block Groups 2024 and Environmental Justice Distressed Municipality 2024. All Census and ACS data used in the creation of these data are the latest available from the Census at time of calculation. Environmental Justice Block Groups 2024 was created from Connecticut block group boundary data located in the Census Bureau's 2024 Block Group TIGER/Line Shapefiles. The poverty data used to determine which block groups qualified as EJ communities (see CT State statute 22a-20a) was based on the Census Bureau's 2023 ACS 5-year estimate. This poverty data was joined with the block group boundaries in ArcPro. Block groups in which the percent of the population below 200% of the federal poverty level was greater than or equal to 30.0 were selected and the resulting selection was exported as a new shapefile. The block groups were then clipped so that only those block groups outside of distressed municipalities were displayed. Maintenance – This layer will be updated annually and will coincide with the annual distressed municipalities update (around August/September). The latest ACS 5-year estimate data should be used to update this layer. Environmental Justice Distressed Municipalities 2024 was created from the Connecticut town boundary data located in the Census Bureau's 2024 TIGER/Line Shapefiles (County Subdivisions). From this shapefile, "select by attribute" was used to select the distressed municipalities by town name (note: the list of 2024 distressed municipalities was provided by the CT Department of Economic and Community Development). The selection was then exported a new shapefile. The “Union” tool was used to unite the new shapefile with tribal lands (American Indian Area Geography) boundary data from the 2024 TIGER/Line files. In the resulting layer, the tribal lands were deleted so only the distressed municipalities remained. Maintenance – This layer will be updated

This resouce contains two spatial datasets.

MPCA Environmental Justice Areas
MPCA Census Tribal Areas

These data represent areas of consideration for MPCA environmental justice efforts. Our goal is to highlight regions where community members are disproportionately impacted by environmental issues. The data fields in this layer are a mix of American Community Survey (ACS) 5-year estimates and calculations performed by MPCA staff. Margins of error are not considered when determining potential areas of consideration.

As an attempt to highlight environmental justice areas of concern, we show census tracts where the estimated percentage of the population that identify as people of color is 40% or greater, the estimated percentage of economically disadvantaged community members is 35% or greater, as well as the estimated percentage of the population that has limited English proficiency is 40% or greater. We also include language information for each census tract and highlight the top three estimated languages spoken by those who report that they do not speak English well.

Income Threshold:
The federal government defines poverty thresholds on an annual basis (https://www.census.gov/data/tables/time-series/demo/income-poverty/historical-poverty-thresholds.html). For MPCA use, we show an income threshold at 2 times the federal poverty threshold.

2022:
2 x $13,590 = $27,180 (individual)
2 x $27,750 = $55,500 (family of four)

This resource also contains Tribal Areas. These areas are derived by taking the maximum extent of two spatial datasets: the U.S. Census Bureau's 2022 TIGER/Line Shapefiles, Current American Indian/Alaska Native/Native Hawaiian Areas for United States; and Minnesota Department of Transportation's Tribal Government in Minnesota.

description: This map service displays raw environmental data for the 12 environmental indicators used in EJSCREEN. The map service displays percentiles for each of the environmental indicators to provide perspective on how a selected location compares to the entire nation. EJSCREEN is an environmental justice screening tool that provides EPA with a nationally consistent approach to screening for potential areas of EJ concern that may warrant further investigation. The EJ indexes are block group level results that combine multiple demographic factors with a single environmental variable (such as proximity to traffic) that can be used to help identify communities living with the greatest potential for negative environmental and health effects. The EJSCREEN tool is currently for internal EPA use only. It is anticipated that as users become accustomed to this new tool, individual programs within the Agency will develop program use guidelines and a community of practice will develop around them within the EPA Geoplatform. Users should keep in mind that screening tools are subject to substantial uncertainty in their demographic and environmental data, particularly when looking at small geographic areas, such as Census block groups. Data on the full range of environmental impacts and demographic factors in any given location are almost certainly not available directly through this tool, and its initial results should be supplemented with additional information and local knowledge before making any judgments about potential areas of EJ concern.; abstract: This map service displays raw environmental data for the 12 environmental indicators used in EJSCREEN.
