Update August 3, 2023: Ten Census Block Groups for field "May 2023 DI Type" were corrected to display "Area under Tribal Jurisdiction". Previously, they were labeled as "Within a Justice 40 Census Tract". While those areas are within Justice 40 Census Tracts, the most correct label based on HB23-1233 DI Definition is "Area under Tribal Jurisdiction". CO EnviroScreen does not provide or display environmental health data for areas under tribal jurisdiction (see FAQ page 4).Impacted Census Block Groups include: 080679404002, 080679403003, 080679403002, 080679403001, 080839411002, 080839411001, 080079404002, 080079404001, 080679404003, 080679404001Colorado EnviroScreen is an environmental justice mapping tool that uses population and environmental factors to calculate an EnviroScreen Score. A higher EnviroScreen Score means the area is more likely to be affected by environmental inequities. This dataset also includes variables for CBGs that qualify as a “Disproportionately Impacted Community” under Colorado law. House Bill 23-1233 adopted a definition that applies to all state agencies, including CDPHE in May 2023. The definition includes census block groups where more than 40% of the population are low-income (meaning that median household income is at or below 200% of the federal poverty line), 50% of the households are housing cost-burdened (meaning that a household spends more than 30% of its income on housing costs like rent or a mortgage), 40% of the population are people of color (including all people who do not identify as non-Hispanic white), or 20% of households are linguistically isolated (meaning that all members of a household that are 14 years old or older have difficulty with speaking English. Also included in this definition are mobile home communities, the Ute Mountain Ute and Southern Ute Indian Reservations, and all areas that qualify as disadvantaged in the federal Climate and Economic Justice Screening Tool. The definition also includes census block groups that experience higher rates of cumulative impacts, which is represented by an EnviroScreen Score (Percentile) above 80. This definition is not part of the EnviroScreen components or score, and does not influence the results presented in the map, charts or table.Prior to May 2023, “Disproportionately Impacted Community” was defined under the Colorado Environmental Justice Act (HB21-1266). The prior “DI Community” variable is also included in this dataset.Click here to access the data download field key. The tool includes scores for each county, census tract, and census block group in Colorado. CDPHE will improve and update the tool in response to feedback and as new data becomes available. Please note that EnviroScreen data for areas under Ute Mountain Ute and Southern Ute tribal jurisdictions are not currently provided though those areas are included in the May 2023 DI Community definition update. Although EnviroScreen provides a robust measure of cumulative environmental burden, it is not a perfect tool. The tool uses limited environmental, health, and sociodemographic data to calculate the EnviroScreen Score. Colorado EnviroScreen does: Show which areas in Colorado are more likely to have higher environmental health injustices. Identify areas in Colorado where government agencies can prioritize resources and work to reduce pollution and other sources of environmental injustice.Provide information to empower communities to advocate to improve public health and the environment. Identify areas that meet the updated definition of “Disproportionately Impacted Community” under House Bill 23-1233 adopted a definition that applies to all state agencies, including CDPHE.Identify areas where the Air Quality Control Commission (AQCC) Regulation (Reg.) Number 3, which governs permitting in disproportionately impacted communities, applies. Identify areas that meet the prior definition of “Disproportionately Impacted Community” under the Colorado Environmental Justice Act (HB21-1266).Colorado EnviroScreen does not: Define a healthy or unhealthy environment. Establish causal associations between environmental risks and health. Define all areas that may be affected by environmental injustice or specific environmental risks. Provide information about an individual person’s health status or environment. Take all environmental exposures into account. Tell us about smaller areas within a census block group that may be more vulnerable to environmental exposures than other areas. Provide information about non-human health or ecosystem risks.
