Aiea, HI population, income and ZIP codes

Aiea CDP is a mid-size town in Hawaii, with 9,155 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #38 of 163 ranked by population — larger than 77% of them. The median age here is 42.9 years against 39.1 nationally, a slightly older 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 Aiea CDP earn a median of $135,286 a year, 72.3% above the national figure of $78,538 and 47% 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 3.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Aiea CDP is valued at $1,053,000, 247.1% above the national figure and 37% above the $768,200 peer median, while median gross rent runs $2,884 a month, 105.1% above the national figure, or roughly $34,608 across a full year. A household on the local median income would put about 25.6% 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 7.8×, 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. 77.1% 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 7.8× 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.
