Kailua Kona, HI

ZIP code 96740 is assigned to Kailua Kona, HI, and falls within Hawaii County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 40,805 people live inside it.

At 168 residents per square mile spread over 242.366 square miles, 96740 reads as a rural area. It is a populous postal code, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.

Household earnings run above the national median. At $94,091, 96740 sits comfortably in the upper half, ahead of 79% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.

Housing in 96740 costs far above the national median. A typical home is valued at $730,600 against a US median of $207,500, and median gross rent runs $1,692 a month. Ownership dominates: 70.9% of occupied homes are owner-occupied, which usually signals an established residential area with relatively low turnover.

The building stock is dominated by detached single-family houses, which account for 60.9% of housing units here. The median construction year is 1988, making the housing here from the later twentieth century. The vacancy rate of 26.0% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews broadly in line with the national age profile, with a median age of 43.2 against 42 nationally. The average household holds 2.88 people, and 68.5% are family households.

Getting to work takes 24.5 minutes on average one way. The dominant mode is drove alone at 66.7% of workers, while 11.1% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 96740 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.

For anyone weighing a move, 96740 offers a compact profile of Kailua Kona: 40,805 residents, a median household income of $94,091, 34.8% of adults holding a bachelor's degree or higher, and an unemployment rate of 3.8%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.

One caution worth repeating: a postal code is not a neighbourhood. 96740 may cover parts of several distinct areas, and a single neighbourhood in Kailua Kona may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
