Twin Lakes, IA population, income and ZIP codes

Twin Lakes CDP is a very small community in Iowa, with 535 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #453 of 1,026 ranked by population — larger than 55% of them. The median age here is 61.3 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 Twin Lakes CDP earn a median of $120,699 a year, 53.7% above the national figure of $78,538 and 78% above the $67,791 median for the 290 Iowa cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Twin Lakes CDP is valued at $543,400, 79.1% above the national figure and 248% above the $156,300 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 4.5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 90% 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 61.3 puts Twin Lakes 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 535 residents, a handful of survey responses moves every median on this page. Compare Twin Lakes CDP against its county rather than against national figures.

The Census withheld gross rent for Twin Lakes 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.
