Petersburg city, IL in context

How this area compares with national benchmarks.

Petersburg city is a small town in Illinois, with 2,590 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #455 of 1,462 ranked by population — larger than 68% of them. The median age here is 38.8 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Petersburg city earn a median of $59,850 a year, 23.8% below the national figure of $78,538 and 19% below the $74,244 median for the 698 Illinois 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 15.5% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Petersburg city is valued at $174,800, 42.4% below the national figure and within a couple of points of the $179,100 peer median, while median gross rent runs $665 a month, 52.7% below the national figure, or roughly $7,980 across a full year. A household on the local median income would put about 13.3% 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. 57.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
