Buffalo, IN population, income and ZIP codes

Buffalo CDP is a very small community in Indiana, with 814 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #405 of 976 ranked by population — larger than 58% of them. The median age here is 56.9 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 Buffalo CDP earn a median of $125,809 a year, 60.2% above the national figure of $78,538 and 104% above the $61,527 median for the 355 Indiana cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Buffalo CDP is valued at $131,000, 56.8% below the national figure and 10% below the $145,600 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1×, 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. 100% 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.

A median age of 56.9 puts Buffalo 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. With 814 residents, a handful of survey responses moves every median on this page. Compare Buffalo CDP against its county rather than against national figures.

The Census withheld gross rent for Buffalo 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.
