Grainfield, KS population, income and ZIP codes

Grainfield city is a very small community in Kansas, with 243 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #400 of 740 ranked by population — larger than 46% of them. The median age here is 43.4 years against 39.1 nationally, a slightly older 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 Grainfield city earn a median of $44,688 a year, 43.1% below the national figure of $78,538 and 30% below the $63,750 median for the 200 Kansas 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 3.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Grainfield city is valued at $85,000, 72% below the national figure and 35% below the $131,300 peer median, while median gross rent runs $713 a month, 49.3% below the national figure, or roughly $8,556 across a full year. A household on the local median income would put about 19.1% 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. 63.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.
