Frontenac, KS population, income and ZIP codes

Frontenac city is a small town in Kansas, with 3,381 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #84 of 740 ranked by population — larger than 88% of them. The median age here is 40 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 Frontenac city earn a median of $56,867 a year, 27.6% below the national figure of $78,538 and 11% below the $63,750 median for the 200 Kansas cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 9.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Frontenac city is valued at $165,400, 45.5% below the national figure and 26% above the $131,300 peer median, while median gross rent runs $847 a month, 39.8% below the national figure, or roughly $10,164 across a full year. A household on the local median income would put about 17.9% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 69% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
