ZIP 83321 in context

How this area compares with national benchmarks.

ZIP 83321 is a very small community in Twin Falls County, Idaho, with 424 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #210 of 280 ranked by population — larger than 25% of them. The median age here is 40.6 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 ZIP 83321 earn a median of $54,861 a year, 30.1% below the national figure of $78,538. 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 9.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 83321 is valued at $200,000, 34.1% below the national figure, while median gross rent runs $1,008 a month, 28.3% below the national figure, or roughly $12,096 across a full year. A household on the local median income would put about 22% 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 3.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 64.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 424 residents, a handful of survey responses moves every median on this page. Compare ZIP 83321 against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.

Reading ZIP 83321 in context

How 83321 sits inside Twin Falls County and Idaho.

ZIP 83321 is tabulated inside Twin Falls County, Idaho, one of 8 ZIP areas the Census publishes for that county and 280 across Idaho. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 83321 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 83321 reports a median household income of $54,861, 12% below the $62,331 county median, and 20% below the $68,377 typical ID ZIP. Owner-occupied homes are valued at a median of $200,000, 16% below the county figure and 33% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,008 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Idaho charges 6% statewide, and local governments overlapping 83321 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 83321 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.
