  • The median household income is $142,778, significantly higher than the national average.
  • Only one street name appears in postal records: Mackeyville Road, reflecting the community's compact rural character.

PO Box Adoption in Rural Pennsylvania

About 69% of the 49 occupied households use PO Boxes at the local post office. That's higher than typical for a community this size, but it makes sense here. Rural carrier routes serve some homes along Mackeyville Road, but many residents who live farther out find it easier to pick up mail at the post office. The mix of PO Boxes and rural delivery reflects how spread out the area is.

Demographics and Economy

The median age here is 40.1 years, and the median household income is $142,778. That's well above the national average. Homes have a median value of $139,600. Eight businesses operate in the area, employing 44 people total. About 18% of workers work from home, which isn't unusual for a rural Pennsylvania community with good internet access.

Postal Service Options

The post office maintains 34 PO Boxes for local use. Unlike some rural areas where PO Boxes are the only option, Mackeyville has both. Residents can choose between having mail delivered to their homes via rural carrier or maintaining a box at the post office. That flexibility works well for a community where some homes are close to the main road and others are tucked away on private drives.

Street Name Patterns

Single Street

With just one street name in postal records, Mackeyville Road represents the entire delivery infrastructure. This single-street designation is common in very small Pennsylvania hamlets where most addresses are simply route numbers or PO Boxes.
