Volcano, HI population, income and ZIP codes

Volcano CDP is a very small community in Hawaii, with 580 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #139 of 163 ranked by population — larger than 14% of them. The median age here is 68 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Volcano CDP earn a median of $72,135 a year, 8.2% below the national figure of $78,538 and 22% below the $92,062 median for the 124 Hawaii cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 10.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Volcano CDP is valued at $602,500, 98.6% above the national figure and 22% below the $768,200 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 8.4×, 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. 94.4% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Home values sit at 8.4× 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. A median age of 68 puts Volcano CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

The Census withheld gross rent for Volcano 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.
