Rockland is a small, affluent retirement community in northern New Castle County, Delaware. With just 223 residents spread across 1.5 square miles, this isn't a typical ZIP code. It's a PO Box Only Zone, meaning there's no street delivery anywhere in the area. The 184 PO Boxes serve 117 households, with the extra boxes supporting surrounding rural areas and the 10 local businesses.
The median age here is 57.1 years, and small household sizes (1.9 people per home) point to empty nesters and retirees. What stands out is the wealth and education: median household income hits $250,000, median home value is $704,900, and every adult (100%) holds at least a bachelor's degree. These are some of Delaware's most expensive and exclusive properties.
Most homes (85 of 154 total housing units) were built before 1939, giving Rockland historic character. Street names like Adams Dam Road, Millrace Lane, and Rockland Mills hint at the area's milling past along the Brandywine watershed. With 97% of homes owner-occupied and only 3 renter-occupied units, this is a settled, stable community.
Mail delivery uses both a city carrier route and a rural route, though all addresses require PO Boxes. The mixed delivery pattern (classified as Urban+Rural) handles the small number of street addresses in the ZIP+4 data. General Delivery is also available at the post office, common in areas without standard street delivery infrastructure.
Street names reference the area's milling heritage along the Brandywine watershed, with Adams Dam, Millrace, and multiple Rockland variations.
ZIP Code 19732 has 223 residents and 117 households (average 1.91 persons per household).
