	2015–2019	2020–2024	Amount of change	Verdict
Median household income	$140,125 (±$16,520)	$147,308 (±$26,220)	+5.1%	No measurable change after inflation
Median home value	$272,300 (±$8,875)	$351,000 (±$25,110)	+28.9%	No measurable change after inflation

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