The Derma post office maintains 74 PO Boxes for 81 residents across 22 households. That's an adoption rate of 3.36—meaning the facility serves more than three times as many boxes as local households. This isn't local service. It's regional infrastructure for surrounding unincorporated areas where carrier delivery doesn't reach.
Calhoun County's rural character explains the pattern. The ZIP spans just 0.056 square miles of incorporated area, but the postal facility serves a much wider geographic footprint. Five rural carrier routes operate from this location, extending mail service to customers who live beyond the tiny community center. Those customers travel to Derma for their mail because no delivery alternative exists closer to home.
The streets tell the story of a minimal town center. South Main Street accounts for most delivery records, with Highway 8 running through as the primary corridor. Pearl Street and Burt Avenue complete the short list. Four streets total. No apartment buildings, no commercial complexes. The Census counts 32 housing units, with 10 sitting vacant. Median age is 26.5, younger than typical rural Mississippi.
This is what true PO Box reliance looks like. Not by choice, but by geography. The high adoption rate doesn't reflect local preference—it reflects the absence of street delivery across the broader service area. Residents from miles around come to these 74 boxes because that's where the mail system reaches them. The post office isn't just serving Derma. It's serving everyone who can't be served anywhere else.
The four-street roster reflects a minimal town center where Highway 8 provides the main corridor. South Main Street, Pearl Street, and Burt Avenue compose the tiny grid—just enough infrastructure to support the regional postal facility that serves surrounding rural areas.
