ZIP code 19720

ZIP 19720 is a small city in New Castle County, Delaware, with 60,593 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it first of 68 ranked by population. The median age here is 39.7 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 19720 earn a median of $75,985 a year, 3.3% below the national figure of $78,538. 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 10.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 19720 is valued at $242,600, 20% below the national figure, while median gross rent runs $1,282 a month, 8.8% below the national figure, or roughly $15,384 across a full year. A household on the local median income would put about 20.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 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. 67.2% 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.

ZIP 19720 is tabulated inside New Castle County, Delaware, one of 29 ZIP areas the Census publishes for that county and 68 across Delaware. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 19720 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 19720 reports a median household income of $75,985, 12% below the $86,240 county median, and 5% below the $79,698 typical DE ZIP. Owner-occupied homes are valued at a median of $242,600, 24% below the county figure and 18% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,282 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Delaware charges 0% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 19720.

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 19720 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.
