What these numbers say together

Nanticoke, MD (ZIP 21840) sits in Wicomico County within the Salisbury metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: High Blood Pressure comes in above the national average at 46.4%. No NCES schools are mapped to this ZIP in the current dataset. 4 colleges and universities serve the area, with median in-state tuition of $9,076. IRS data shows average household income (AGI) of $85,175, well above the ~$45K national average per return. The most recent FEMA disaster declaration here was winter storm-related (SEVERE WINTER STORM, 2026). 29.7% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Maryland levies a graduated state income tax (top rate 5.75%); a household at the local median AGI of $85,175 would pay roughly $2,939/year before deductions. IRS migration data (2022-2023) shows a net loss of 645 residents (308 households) — the ZIP's primary county is shrinking. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: fair market rent of $1,380 for a two-bedroom, a typical home value of $258,784, up 6.5% over the past year, 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.

The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.

One concrete reading worth keeping: Depression prevalence sits lower the national rate at 18.8%. 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.
