2015–2019 and 2020–2024 American Community Survey 5-year estimates
	2015–2019	2020–2024	Amount of change	Verdict
Median home value	$648,700 (±$20,027)	$804,600 (±$50,264)	+24.0%	No measurable change 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.
