Income against housing costs since 2015–2019

2015–2019 and 2020–2024 American Community Survey 5-year estimates
	2015–2019	2020–2024	Amount of change	Verdict
Median household income	$113,578 (±$9,867)	$138,162 (±$8,821)	+21.6%	No measurable change after inflation
Median gross rent	$1,153 (±$45)	$2,139 (±$434)	+85.5%	Up after inflation
Median home value	$302,900 (±$10,880)	$397,000 (±$20,064)	+31.1%	Up after inflation

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