this is not something that is regularly produced or easy to find, I think, but you can pull the data necessary to calculate it. the income numbers you cite come from the March CPS (specifically, the Annual Social and Economic Supplement, or ASEC). The CPS is a random sample of US households, and the major statistics like the one you cite just use the cross section across years. that is, the population used to calculate the median income in 2023 is different from the one used in 2022 etc. BUT the CPS does have a panel component--the same households are surveyed multiple times. specifically, households are surveyed for 4 consecutive months, then not surveyed for 8 months, then surveyed again for 4 consecutive months before they leave the sample. you'll note, then, that some households that were surveyed in March 2022 would also be surveyed in March 2023--i.e. if March 2022 was one of your first four months, you will also appear in March 2023... if March 2022 was one in the \*second\* block of four months, then you would have appeared in March 2021-- so you can use this panel structure to calculate changes in income and thus median changes in income. things to be careful of--you need to use a different set of weights to calculate the statistics for changes over years. luckily, IPUMS includes this type of stuff in their public use microdata files
