Oconomowoc city, WI in context

How this area compares with national benchmarks.

Oconomowoc city is a mid-size town in Wisconsin, with 18,385 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #46 of 807 ranked by population — larger than 94% of them. The median age here is 43.1 years against 39.1 nationally, a slightly older 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 Oconomowoc city earn a median of $105,833 a year, 34.8% above the national figure of $78,538 and 43% above the $73,880 median for the 395 Wisconsin cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 7.2% of residents here, below the 12.4% national rate.

A household on the local median income would put about 14% 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 68% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners.
