Average vs median home price — what's the difference?
The figure $263,300 is the median home value reported by the US Census Bureau — the middle value when every owner-occupied home in Illinois is sorted by price. Median is the standard measure used in housing reporting because it is not skewed by a small number of very expensive properties. The "average" home price searched for online almost always refers to this median value; true arithmetic averages tend to be 10–30% higher than the median in markets with high-end outliers, but the Census does not publish that figure.
For Illinois specifically, the Census also reports a median monthly rent of $1,274 and a price-to-income ratio of 3.2×. Both are sourced from the same 2020–2024 ACS 5-Year Estimates release.
