Colfax city, IA in context

How this area compares with national benchmarks.

Colfax city is a small town in Iowa, with 2,089 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #160 of 1,026 ranked by population — larger than 84% of them. The median age here is 33.3 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 Colfax city earn a median of $82,878 a year, 5.5% above the national figure of $78,538 and 22% above the $67,791 median for the 290 Iowa cities we cover. 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 10.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Colfax city is valued at $160,500, 47.1% below the national figure and 3% above the $156,300 peer median, while median gross rent runs $830 a month, 41% below the national figure, or roughly $9,960 across a full year. A household on the local median income would put about 12% 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. 70.9% 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.
