Captain Cook CDP, HI in context
How this area compares with national benchmarks.
Captain Cook CDP is a small town in Hawaii, with 3,751 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #70 of 163 ranked by population — larger than 57% of them. The median age here is 40.7 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 Captain Cook CDP earn a median of $124,551 a year, 58.6% above the national figure of $78,538 and 35% 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 9% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Captain Cook CDP is valued at $642,500, 111.8% above the national figure and 16% below the $768,200 peer median, while median gross rent runs $1,818 a month, 29.3% above the national figure, or roughly $21,816 across a full year. A household on the local median income would put about 17.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 5.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 59.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
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.
