ZIP 19717 in context
How this area compares with national benchmarks.
ZIP 19717 is a mid-size town in New Castle County, Delaware, with 6,522 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #44 of 68 ranked by population — larger than 35% of them. The median age here is 19.4 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 19717 earn a median of not published a year. 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 Poverty reaches an unpublished share of residents here.
The typical owner-occupied home in ZIP 19717 is valued at not published, while median gross rent runs not published a month. The homeownership rate is not published. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
A median age of 19.4 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.
The Census withheld household income, home value, gross rent, poverty rate for ZIP 19717 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
