Key Facts
  • The post office maintains 96 PO Boxes for just 47 households, indicating this facility serves surrounding rural areas beyond town limits
  • This is a PO Box Only Zone where street delivery is unavailable across the broader service area, making the post office essential for rural residents
  • 71% of homes (47 of 66 units) were built before 1939, making this one of Kentucky's most historically intact small towns
  • With a median household income of $11,786, this is a working-class community where 35% of housing consists of mobile homes
  • Despite being classified as a PO Box ZIP, the town has limited street delivery on one city route and one rural route serving Main Street and surrounding streets

A Compact Regional Hub

North Middletown sits in northeastern Bourbon County, Kentucky, covering just 0.025 square miles. This tiny incorporated town of 116 residents serves as a regional mail hub for surrounding rural areas. The post office maintains 96 PO Boxes for only 47 local households, a 2.04 adoption rate that shows the facility serves families from well beyond the town limits.

Why PO Boxes Serve the Countryside

This is a PO Box Only Zone. Street delivery doesn't reach the rural areas that depend on this post office. Residents from the surrounding countryside travel to North Middletown to collect their mail, creating a regional service pattern uncommon in such a small community.

Historic Working-Class Character

The town itself is historic and working class. Of the 66 total housing units, 47 were built before 1939. That's 71% of all homes predating World War II. Mobile homes make up 23 of the units (35% of housing stock). Median household income stands at $11,786, well below state and national averages. Home values are modest at a median of $95,000.

Limited Street Delivery Within Town

Despite the PO Box classification, limited street delivery does exist within town. The USPS maintains one city carrier route and one rural route serving addresses on Main Street, Liberty Avenue, Vimont Street, and several other small streets. Mail delivery follows an Urban+Rural pattern, mixing in-town stops with countryside routes. However, for the broader service area, PO Boxes remain the only option.

Demographics

The demographics are typical of rural Kentucky. Median age is 36.7 years. All residents in the census sample were born in the United States. The population is predominantly white (97 of 116 residents, or 84%). Only 3 residents are under 18, while 9 are ages 18 to 24. This isn't a retirement community; it's a stable small town with modest incomes and old housing stock.
