Boise, ID population, income and ZIP codes

Boise City city is a mid-size city in Idaho, with 235,701 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it first of 236 ranked by population. The median age here is 38.2 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 Boise City city earn a median of $81,308 a year, 3.5% above the national figure of $78,538 and 27% above the $63,864 median for the 100 Idaho cities we cover. 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 10.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Boise City city is valued at $456,000, 50.3% above the national figure and 68% above the $271,500 peer median, while median gross rent runs $1,359 a month, 3.3% below the national figure, or roughly $16,308 across a full year. A household on the local median income would put about 20.1% 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 5.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 63% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
