ZIP code 83706

ZIP 83706 is a small city in Ada County, Idaho, with 36,183 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #16 of 280 ranked by population — larger than 94% of them. The median age here is 29.8 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 83706 earn a median of $81,101 a year, 3.3% above the national figure of $78,538. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 18.3% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 83706 is valued at $488,900, 61.1% above the national figure, while median gross rent runs $1,378 a month, 2% below the national figure, or roughly $16,536 across a full year. A household on the local median income would put about 20.4% 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 6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 48.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 29.8 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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 83706 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 83706 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 83706 reports a median household income of $81,101, 7% below the $87,656 county median, and 19% above the $68,377 typical ID ZIP. Owner-occupied homes are valued at a median of $488,900, close to the county figure and 65% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,378 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 83706 carries 6% at the register, assembled from the Boise jurisdiction stack: the Idaho state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 83706 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

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 83706 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.
