Nampa, ID population, income and ZIP codes

Nampa city is a mid-size city in Idaho, with 106,289 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #3 of 236 ranked by population — larger than 99% of them. The median age here is 34.1 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 Nampa city earn a median of $72,122 a year, 8.2% below the national figure of $78,538 and 13% above the $63,864 median for the 100 Idaho cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 10.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Nampa city is valued at $332,500, 9.6% above the national figure and 22% above the $271,500 peer median, while median gross rent runs $1,340 a month, 4.7% below the national figure, or roughly $16,080 across a full year. A household on the local median income would put about 22.3% 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 4.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 71.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
