Mammoth Spring, AR population, income and ZIP codes

Mammoth Spring city is a very small community in Arkansas, with 871 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #229 of 625 ranked by population — larger than 63% of them. The median age here is 38.5 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 Mammoth Spring city earn a median of $30,800 a year, 60.8% below the national figure of $78,538 and 38% below the $49,306 median for the 209 Arkansas 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 24% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Mammoth Spring city is valued at $99,400, 67.2% below the national figure and 23% below the $128,900 peer median, while median gross rent runs $329 a month, 76.6% below the national figure, or roughly $3,948 across a full year. A household on the local median income would put about 12.8% 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 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 73.1% 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.
