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	$74,458 (±$6,916)	$113,707 (±$6,569)	+52.7%	Up after inflation
Median gross rent	$1,690 (±$87)	$2,071 (±$247)	+22.5%	No measurable change after inflation
Median home value	$275,800 (±$7,472)	$436,400 (±$12,914)	+58.2%	Up after inflation

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

Prices (the CPI-U, US Bureau of Labor Statistics) rose 22.7% between 2019 and 2024, so a dollar figure’s verdict compares the two after raising the earlier one by that much, using the Census Bureau’s test for a difference.

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