Kirby, AR population, income and ZIP codes

Kirby CDP is a very small community in Arkansas, with 582 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #276 of 625 ranked by population — larger than 55% of them. The median age here is 47.2 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 Kirby CDP earn a median of $77,955 a year, essentially level with the national figure of $78,538 and 58% above the $49,306 median for the 209 Arkansas 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 11.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Kirby CDP is valued at $111,200, 63.3% below the national figure and 14% below the $128,900 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.4×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 85.1% 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. 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.

With 582 residents, a handful of survey responses moves every median on this page. Compare Kirby CDP against its county rather than against national figures.

The Census withheld gross rent for Kirby 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.
