U.S. DOT Equitable Transportation Community (ETC) Explorer is an interactive web application that uses 2020 Census Tracts and data, to explore the cumulative burden communities experience, as a result of underinvestment in transportation, in the following five components: Transportation Insecurity, Climate and Disaster Risk Burden, Environmental Burden, Health Vulnerability, and Social Vulnerability.

DOT considers Census tracts to be “disadvantaged” in communities with a Final Index Score greater than 0.65 (65th percentile). USDOT considers communities as “disadvantaged" in a component or indicator if their percentile score is greater than 0.65 (65th percentile) in that area.

Census Tracts/projects areas at “0%” are considered the least disadvantaged and “100%” are the most. DOT considers a census tract to be experiencing disadvantage if the overall index score places it in the 65% (or higher) of all US census tracts. The 65% cutoff was chosen to be consistent with CEJST, which prioritizes tracts at the 65th percentile or above for CJEST’s low-income indicator.

- Component Scores are distinct from Indicator Scores. For more information please see - Understanding the Data.
