How renting in O'Fallon has changed since 2015–2019

2015–2019 and 2020–2024 American Community Survey 5-year estimates
	2015–2019	2020–2024	Amount of change	Verdict
Households that rent	17.8% (±1.2 points)	19.0% (±1.6 points)	+1.2 percentage points	Not a measurable change
Median gross rent	$1,103 (±$40)	$1,443 (±$47)	+30.8%	Up after inflation
Median household income	$90,025 (±$2,165)	$110,443 (±$5,849)	+22.7%	No measurable change after inflation

The Census Bureau publishes 2015–2019 dollars in 2019 dollars and 2020–2024 dollars in 2024 dollars.
