Herculaneum city, MO in context
How this area compares with national benchmarks.
Herculaneum city is a small town in Missouri, with 4,925 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #144 of 1,082 ranked by population — larger than 86% of them. The median age here is 38.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Herculaneum city earn a median of $88,778 a year, 13% above the national figure of $78,538 and 60% above the $55,543 median for the 374 Missouri cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 5.4% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in Herculaneum city is valued at $222,100, 26.8% below the national figure and 46% above the $152,400 peer median, while median gross rent runs $2,065 a month, 46.9% above the national figure, or roughly $24,780 across a full year. A household on the local median income would put about 27.9% 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 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 88.4% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.
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.
