What these numbers say together
Fallston, NC (ZIP 28042) sits in Cleveland County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Depression comes in above the national average at 27.9%. NCES lists 1 schools serving the area, 1 non-charter. 8 colleges and universities serve the area, with median in-state tuition of $16,550. Local establishments report average pay of $28,828 per worker (Census ZBP) — below the US average. FEMA has issued 20 federal disaster declarations affecting this ZIP since 1977 — a high-frequency exposure profile. Annual precipitation averages 50.4" — a wet-climate ZCTA per NOAA's 1991–2020 Normals. County Health Rankings reports 12,476 years of potential life lost per 100,000 (2025) — well above the national county median. Fast-food restaurants outnumber grocery stores roughly 4-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. IRS migration data (2022-2023) shows a net gain of 1,157 residents (499 households) — the ZIP's primary county is growing. 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 $930 for a two-bedroom, a typical home value of $206,613, down 3.9% over the past year, and a 53.1% 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.
One concrete reading worth keeping: Depression prevalence sits higher the national rate at 27.9%. 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.
