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.
