Greenville, DE population, income and ZIP codes

Greenville CDP is a small town in Delaware, with 3,100 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #30 of 79 ranked by population — larger than 62% of them. The median age here is 48.7 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Greenville CDP earn a median of $139,541 a year, 77.7% above the national figure of $78,538 and 86% above the $75,000 median for the 54 Delaware cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 4.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Greenville CDP is valued at $1,003,100, 230.6% above the national figure and 258% above the $280,200 peer median, while median gross rent runs $1,584 a month, 12.7% above the national figure, or roughly $19,008 across a full year. A household on the local median income would put about 13.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 7.2×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 51.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Home values sit at 7.2× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
