About ZIP code 58566

The housing stock consists of predominantly single-family detached homes. Most homes were built in the 1970s, giving the area an established character. Owner-occupancy sits near the national average at 63%.

The gap between median ($46,890) and mean household income suggests income inequality — a small number of higher earners pull the average up. 32% of households receive Social Security income, suggesting a notable retiree or disability population.

The dominant occupation class is production, transportation, and material moving, with education and healthcare as the leading industry. An above-average commute of 36 minutes suggests many residents work outside the immediate area.
