Health Vulnerability Statement

All communities included in this report are designated as “underserved” by MDEnviroScreen. Notably, Turner Station, Cheverly, Cedar Heights, Curtis Bay, and areas near HCNR, and HU-B are further classified as “overburdened,” meaning they face a cumulative impact of three or more environmental or health stressors.

Critical sensitive population indicators (75th Percentile or higher):

Due to these compounding health disparities and socio-environmental stressors, the reported Air Quality Health Index (AQHI) represents a conservative baseline; the actual risk to residents in these tracts is likely higher than the index alone suggests.
