This isn't a traditional town. The ZIP includes aliases for "Old Camp" and "New Camp," names that reference the area's coal mining past when temporary settlements housed miners and their families. Today, 169 occupied housing units dot the landscape, connected by rural carrier routes rather than city delivery. Two rural routes serve the area, reaching homes scattered along Kennedy Street, North Mayor Caliper Drive, and numbered streets that hint at a planned community that never fully materialized.
The delivery pattern here is entirely rural. Seven rural route records and no city carrier routes mean mail comes by truck to roadside boxes and PO Boxes at the post office. For the 140 residential delivery points tracked in spatial data, 138 are PO Boxes and only 2 are street addresses. That's nearly complete PO Box adoption, which makes sense when homes sit far apart across open country.
Most residents work in nearby towns. With a median household income of $36,250 and median home values at $75,000, this is an affordable rural area where 50 people commute to Williamson County jobs. The community skews older, with a median age of 46.5 years. Of the 198 total housing units, 169 are occupied year-round, leaving 29 vacant. Only one person works from home according to census data, reflecting limited internet infrastructure common in rural southern Illinois.
The street names show a planned town grid with numbered streets (7th, 8th, 12th) that was never fully developed. Kennedy Street and Mayor Caliper Drive suggest civic aspirations for this former mining settlement. The small number of delivery records per street (1-2 each) confirms the sparse, rural character of what remains today.
ZIP Code 62921 has 342 residents and 169 households (average 2.02 persons per household). The median age is 46.5 years, significantly older than the state (38.8) and significantly older than the nation (38.8). The gender split is 45.9% male and 54.1% female, which is lower than the national male share (49.1%), making this a female-majority area. Largest groups are White (53.2%, much lower than the state average of 61.4% and well below the national average of 61.6%) and Black or African American (39.2%, much higher than the state average of 14.1% and well above the national average of 12.4%); Hispanic or Latino residents make up 0.9%, which is much lower than the national average (18.7%), and Black or African American share is much higher than both the state (14.1%) and national averages (12.4%).
