ZIP code 19804

ZIP 19804 is a mid-size town in New Castle County, Delaware, with 18,231 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #20 of 68 ranked by population — larger than 71% of them. The median age here is 41 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 19804 earn a median of $76,204 a year, 3% below the national figure of $78,538. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 8.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 19804 is valued at $244,700, 19.3% below the national figure, while median gross rent runs $1,157 a month, 17.7% below the national figure, or roughly $13,884 across a full year. A household on the local median income would put about 18.2% 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 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 75.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 19804 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
