New Vienna, IA population, income and ZIP codes

New Vienna city is a very small community in Iowa, with 377 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #551 of 1,026 ranked by population — larger than 46% of them. The median age here is 47.1 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 New Vienna city earn a median of $90,938 a year, 15.8% above the national figure of $78,538 and 34% above the $67,791 median for the 290 Iowa 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 5.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in New Vienna city is valued at $176,800, 41.7% below the national figure and 13% above the $156,300 peer median, while median gross rent runs $763 a month, 45.7% below the national figure, or roughly $9,156 across a full year. A household on the local median income would put about 10.1% 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 1.9×, 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. 89.2% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
