County Health Rankings reports 10,529 years of potential life lost per 100,000 (2025) — well above the national county median. 26.6% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap.

Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: fair market rent of $1,830 for a two-bedroom and a low 0.0% poverty rate. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

Notable: fair market rent of $1,830 for a two-bedroom and a low 0.0% poverty rate. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
Both surfaces skew lighter than national averages. That isn’t a verdict — small-area estimates compress real neighborhood-level texture, and a single ZIP reading can miss a district line or a hospital corridor sitting just outside it. Treat this as a starting point for fieldwork, not a conclusion.
One concrete reading worth keeping: Depression prevalence sits higher the national rate at 32.6%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.

The Social Vulnerability Index uses U.S. Census data to identify communities most at risk during public health emergencies and natural disasters. Higher percentiles indicate greater vulnerability. Tract-level scores are aggregated to this ZCTA via Census 2020 ZCTA→Tract crosswalk, weighted by land-area share. Source: atsdr.cdc.gov. Public domain.
