Median household income	$40,000 (±$18,961)	$69,028 (±$22,414)	+72.6%	No measurable change after inflation
Median gross rent	$514 (±$111)	$636 (±$185)	+23.7%	No measurable change after inflation
Median home value	$86,100 (±$5,129)	$108,100 (±$13,694)	+25.6%	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.
