ZIP 83840 in context

How this area compares with national benchmarks.

ZIP 83840 is a very small community in Bonner County, Idaho, with 649 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #183 of 280 ranked by population — larger than 34% of them. The median age here is 38.2 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 ZIP 83840 earn a median of $69,125 a year, 12% 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 12.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 83840 is valued at $286,700, 5.5% below the national figure, while median gross rent runs $1,548 a month, 10.1% above the national figure, or roughly $18,576 across a full year. A household on the local median income would put about 26.9% 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 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 81.9% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.

With 649 residents, a handful of survey responses moves every median on this page. Compare ZIP 83840 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 83840 in context

How 83840 sits inside Bonner County and Idaho.

ZIP 83840 is tabulated inside Bonner County, Idaho, one of 16 ZIP areas the Census publishes for that county and 280 across Idaho. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. 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 83840 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 83840 reports a median household income of $69,125, close to the $68,595 county median, and close to the $68,377 typical ID ZIP. Owner-occupied homes are valued at a median of $286,700, 40% below the county figure and 3% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,548 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 83840 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 83840 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.
