Wainiha, HI population, income and ZIP codes

Wainiha CDP is a very small community in Hawaii, with 319 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #148 of 163 ranked by population — larger than 9% of them. The median age here is 31.2 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Wainiha CDP earn a median of $103,906 a year, 32.3% above the national figure of $78,538 and 13% 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 5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Wainiha CDP is valued at $918,000, 202.6% above the national figure and 20% above the $768,200 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 8.8×, 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. 67.1% 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.

Home values sit at 8.8× 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. With 319 residents, a handful of survey responses moves every median on this page. Compare Wainiha CDP against its county rather than against national figures.

The Census withheld gross rent for Wainiha CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
