Ko Olina, HI population, income and ZIP codes

Ko Olina CDP is a small town in Hawaii, with 1,677 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #106 of 163 ranked by population — larger than 35% of them. The median age here is 43.9 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Ko Olina CDP earn a median of $125,577 a year, 59.9% above the national figure of $78,538 and 36% above the $92,062 median for the 124 Hawaii 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 6.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Ko Olina CDP is valued at $885,500, 191.9% above the national figure and 15% above the $768,200 peer median, while median gross rent runs $3,501 a month, 149% above the national figure, or roughly $42,012 across a full year. A household on the local median income would put about 33.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. 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. 63.5% 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.

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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
