Granville, IA population, income and ZIP codes

Granville city is a very small community in Iowa, with 255 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #648 of 1,026 ranked by population — larger than 36% of them. The median age here is 59.9 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 Granville city earn a median of $68,958 a year, 12.2% below the national figure of $78,538 and within a couple of points of the $67,791 median for the 290 Iowa cities we cover. 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 6.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Granville city is valued at $156,300, 48.5% below the national figure and within a couple of points of the $156,300 peer median, while median gross rent runs $1,089 a month, 22.5% below the national figure, or roughly $13,068 across a full year. A household on the local median income would put about 19% 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 2.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 91.6% 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.

A median age of 59.9 puts Granville city well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 255 residents, a handful of survey responses moves every median on this page. Compare Granville city against its county rather than against national figures.

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.
