ZIP 83623 in context
How this area compares with national benchmarks.
ZIP 83623 is a small town in Elmore County, Idaho, with 1,637 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #126 of 280 ranked by population — larger than 55% of them. The median age here is 48 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 83623 earn a median of $56,111 a year, 28.6% below 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 22.8% 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 ZIP 83623 is valued at $191,900, 36.8% below the national figure, while median gross rent runs $725 a month, 48.4% below the national figure, or roughly $8,700 across a full year. A household on the local median income would put about 15.5% 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 69.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.
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 83623 in context
How 83623 sits inside Elmore County and Idaho.
ZIP 83623 is tabulated inside Elmore 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 83623 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 83623 reports a median household income of $56,111, 23% below the $72,411 county median, and 18% below the $68,377 typical ID ZIP. Owner-occupied homes are valued at a median of $191,900, 46% below the county figure and 35% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $725 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 83623 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 83623 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.

What a purchase inside this ZIP costs at checkout.

Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
