Mililani Town, HI population, income and ZIP codes

Mililani Town CDP is a small city in Hawaii, with 27,495 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #8 of 163 ranked by population — larger than 95% of them. The median age here is 45.8 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Town CDP earn a median of $124,123 a year, 58% above the national figure of $78,538 and 35% above the $92,062 median for the 124 Hawaii 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 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Mililani Town CDP is valued at $884,800, 191.6% above the national figure and 15% above the $768,200 peer median, while median gross rent runs $2,303 a month, 63.8% above the national figure, or roughly $27,636 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 7.1×, 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. 82.5% 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. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Home values sit at 7.1× 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.

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.
