Washington County · Hagerstown-Martinsburg, MD-WV · Population 41
St. James, MD (ZIP 21781) sits in Washington County within the Hagerstown-Martinsburg metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: High Blood Pressure comes in below the national average at 19.0%. No NCES schools are mapped to this ZIP in the current dataset. 6 colleges and universities serve the area, with median in-state tuition of $26,010. Social vulnerability is low in this ZIP at the 8th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. The most recent FEMA disaster declaration here was winter storm-related (SEVERE WINTER STORM, 2026). County Health Rankings reports 10,710 years of potential life lost per 100,000 (2025) — well above the national county median. 28.6% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. New residents arriving here predominantly come from Frederick County, MD (IRS SOI Migration, 2022-2023). 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 $1,240 for a two-bedroom and a 100.0% poverty rate (well above the ~12% US average). 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.
