  • 88% of homes are owner-occupied, indicating stable, long-term residents rather than a transient population.

Community Overview

Osgood sits in Darke County, Ohio, a compact village covering just half a square mile in the state's western farmland. With 284 residents and 105 households, it's a tight-knit community where nearly everyone owns their home. Homeownership runs at 88%, and the median home value of $225,000 puts it solidly middle-class for rural Ohio.

PO Box-Only Delivery

This is a PO Box Only Zone. Despite having both city and rural carrier routes operating from the post office, there's no alternative delivery option. Residents pick up their mail at the post office or don't get it at all. The facility maintains 113 PO Boxes for 105 local households, giving it a 1.08 adoption rate. That slight surplus means the Osgood post office serves a few families from surrounding areas who use it as their mailing address.

Village Character

Street names tell the story of a traditional Ohio village grid: W Main St, E Main St, Church St, Washington St, North St, Water St. These aren't subdivisions or cul-de-sacs. They're the bones of a town platted generations ago. The median age of 35.5 years suggests young families, not retirees. Median household income tops $100,000, well above Ohio's average.

A Prosperous Community with Historic Postal Service

What makes Osgood unusual isn't its size or demographics. It's the combination of relative affluence with mandatory PO Box service. This isn't a remote mountain community or desert outpost. It's a prosperous small village where the postal infrastructure never evolved past the post office pickup window.
