ZIP 83429 in context

How this area compares with national benchmarks.

ZIP 83429 is a very small community in Fremont County, Idaho, with 742 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #177 of 280 ranked by population — larger than 36% of them. The median age here is 66.9 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 83429 earn a median of $79,750 a year, 1.5% above the national figure of $78,538. 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 6.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 83429 is valued at $473,300, 56% above the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 5.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 98.4% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 66.9 puts ZIP 83429 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 742 residents, a handful of survey responses moves every median on this page. Compare ZIP 83429 against its county rather than against national figures.

The Census withheld gross rent for ZIP 83429 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

Reading ZIP 83429 in context

How 83429 sits inside Fremont County and Idaho.

ZIP 83429 is tabulated inside Fremont County, Idaho, one of 6 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 83429 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 83429 reports a median household income of $79,750, close to the $80,094 county median, and 17% above the $68,377 typical ID ZIP. Owner-occupied homes are valued at a median of $473,300, 75% above the county figure and 59% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published 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 83429 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 83429 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.
