ZIP code 83646

ZIP 83646 is a small city in Ada County, Idaho, with 74,522 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it first of 280 ranked by population. The median age here is 37.5 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in ZIP 83646 earn a median of $101,040 a year, 28.7% above 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 6.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 83646 is valued at $488,000, 60.8% above the national figure, while median gross rent runs $1,814 a month, 29% above the national figure, or roughly $21,768 across a full year. A household on the local median income would put about 21.5% 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 4.8×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 81.4% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.

ZIP 83646 is tabulated inside Ada County, Idaho, one of 16 ZIP areas the Census publishes for that county and 280 across Idaho. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. 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 83646 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 83646 reports a median household income of $101,040, 15% above the $87,656 county median, and 48% above the $68,377 typical ID ZIP. Owner-occupied homes are valued at a median of $488,000, close to the county figure and 64% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,814 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 83646 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 83646 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.
