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	$114,250 (±$19,028)	$199,167 (±$27,343)	+74.3%	Up after inflation
Median gross rent	$3,050 (±$1,247)	$2,750 (±$1,033)	−9.8%	No measurable change after inflation
Median home value	$655,500 (±$19,811)	$1,058,200 (±$52,812)	+61.4%	Up after inflation

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

The two periods do not overlap, as the Census Bureau recommends for 5-year estimates.
