Roughly 7,400 people and climbing — Millsboro is the second fastest-growing town in Sussex County, ranking second among all fifty-seven Delaware municipalities for residential building permits in 2020, and local realtors credit one simple fact: developers figured out Millsboro is a thirty-minute drive to Rehoboth and Bethany at a real discount to the beach.

Median household income reached $78,707 in 2024, homeownership runs 67.8%, and the housing numbers tell the value story: median property value sits around $332,600 — almost exactly the national median — while single-family homes sell at a median near $435,000 against a Sussex County figure of about $480,000. The age mix is the town's defining feature: roughly a quarter of residents are 65 or older, and out in Long Neck the census puts the 65-plus share at 44.3% with a median age of 62.4 — Millsboro has become one of Sussex County's genuine retirement magnets, close enough to the beaches to visit, far enough to afford.

The working side of town is anchored by three employers — Mountaire Farms, Allen Harim Foods, and Merck Animal Health — poultry and animal health, the industries that built modern Millsboro the way the mills built the original after Elisha Dickerson dammed the river at Rock Hole in 1792. Add one modern wrinkle: about 8% of the workforce now telecommutes, high for a town this size, part of the beach-adjacent migration reshaping the county. The growth isn't only 55+ communities either — young families keep buying in for the Indian River schools and the price gap, which is why the town manages to get older and younger at the same time.

For anyone doing the beach math, that gap is the whole pitch: Rehoboth's median property runs $1.49 million, four and a half times Millsboro's, for a difference of thirty minutes on Route 24.

But the growth isn't only 55+ communities: young families keep buying in for the Indian River schools and the price gap, which is why the town manages to get older and younger at the same time. A lot of the workforce that runs the beach towns lives here too — Millsboro sits in the inland ring that staffs the resort economy, close enough to commute down Route 24, far enough that a paycheck covers a mortgage.

Healthcare runs closer than people expect for a town this size: Beebe's South Coastal emergency department serves the immediate area, with the main Beebe campus in Lewes and TidalHealth's network both within half an hour — which matters in a town where a quarter of your neighbors are past 65. Community life is the fire company, the churches, Cupola Park's concert calendar, the library, and the kind of small-town institutions that predate every master-planned community by a century. Down-to-earth is the phrase the town government itself uses, and it fits: this is a real working town, not a resort — a place where the poultry trucks and the beach traffic share Route 113, and where the pond that started everything in 1792 is still the calm center of the map.
