Kapolei CDP, HI in context

How this area compares with national benchmarks.

Kapolei CDP is a mid-size town in Hawaii, with 23,033 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #11 of 163 ranked by population — larger than 93% of them. The median age here is 33.4 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 Kapolei CDP earn a median of $129,260 a year, 64.6% above the national figure of $78,538 and 40% 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 8.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Kapolei CDP is valued at $720,600, 137.5% above the national figure and 6% below the $768,200 peer median, while median gross rent runs $2,507 a month, 78.3% above the national figure, or roughly $30,084 across a full year. A household on the local median income would put about 23.3% 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 5.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 78.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.
