Le Mars, IA population, income and ZIP codes

Le Mars city is a mid-size town in Iowa, with 10,597 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #39 of 1,026 ranked by population — larger than 96% of them. The median age here is 39.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Le Mars city earn a median of $72,381 a year, 7.8% below the national figure of $78,538 and 7% 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 8.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Le Mars city is valued at $202,200, 33.4% below the national figure and 29% above the $156,300 peer median, while median gross rent runs $908 a month, 35.4% below the national figure, or roughly $10,896 across a full year. A household on the local median income would put about 15.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 62.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
