How renting in Swansea has changed since 2015–2019

2015–2019 and 2020–2024 American Community Survey 5-year estimates
	2015–2019	2020–2024	Amount of change	Verdict
Households that rent	26.3% (±3.5 points)	26.6% (±4.6 points)	+0.3 percentage points	Not a measurable change
Median gross rent	$1,062 (±$90)	$1,137 (±$85)	+7.1%	Down after inflation
Median household income	$77,517 (±$8,313)	$91,587 (±$13,281)	+18.2%	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.
