La Harpe, IL population, income and ZIP codes

La Harpe city is a small town in Illinois, with 1,085 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #677 of 1,462 ranked by population — larger than 53% of them. The median age here is 50.1 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 La Harpe city earn a median of $49,028 a year, 37.6% below the national figure of $78,538 and 34% below the $74,244 median for the 698 Illinois 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 9.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in La Harpe city is valued at $84,200, 72.2% below the national figure and 53% below the $179,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.7×, 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. 84% 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.

A median age of 50.1 puts La Harpe city 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 La Harpe city 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.
