St. John town, IN in context

How this area compares with national benchmarks.

St. John town is a mid-size town in Indiana, with 21,639 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #47 of 976 ranked by population — larger than 95% of them. The median age here is 41.4 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 St. John town earn a median of $127,449 a year, 62.3% above the national figure of $78,538 and 107% above the $61,527 median for the 355 Indiana 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 2.3% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in St. John town is valued at $370,800, 22.2% above the national figure and 155% above the $145,600 peer median, while median gross rent runs $971 a month, 30.9% below the national figure, or roughly $11,652 across a full year. A household on the local median income would put about 9.1% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 98.1% 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. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.
