Mililani Mauka, HI population, income and ZIP codes

Mililani Mauka CDP is a mid-size town in Hawaii, with 21,967 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #13 of 163 ranked by population — larger than 92% of them. The median age here is 38.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Mililani Mauka CDP earn a median of $139,564 a year, 77.7% above the national figure of $78,538 and 52% above the $92,062 median for the 124 Hawaii cities we cover. 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 3.3% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Mililani Mauka CDP is valued at $901,800, 197.2% above the national figure and 17% above the $768,200 peer median, while median gross rent runs $2,389 a month, 69.9% above the national figure, or roughly $28,668 across a full year. A household on the local median income would put about 20.5% 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 6.5×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 76.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 6.5× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

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.
