ZIP code 83448

ZIP 83448 is a small town in Madison County, Idaho, with 3,074 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #90 of 280 ranked by population — larger than 68% of them. The median age here is 27.6 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 ZIP 83448 earn a median of $77,564 a year, 1.2% below the national figure of $78,538. 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 9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 83448 is valued at $331,100, 9.1% above the national figure, while median gross rent runs $1,356 a month, 3.6% below the national figure, or roughly $16,272 across a full year. A household on the local median income would put about 21% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 72.8% 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.

A median age of 27.6 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.

Idaho charges 6% statewide, and local governments overlapping 83448 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 83448 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
