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	$70,625 (±$14,000)	$91,250 (±$13,881)	+29.2%	No measurable change after inflation
Median home value	$139,900 (±$25,390)	$154,100 (±$17,768)	+10.2%	No measurable change after inflation

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