This should be a pretty easy one. Every year, the College Board puts out data on college tuition and financial aid. It's a great service, but of course it's all spreadsheets. Not fun to work with. But you can interact with the data below.
Four views for you to look at:
View one is just ranks: Where does your state flagship rank on tuition and fees for residents and non-residents? Just pick which type of tuition you want to see, then use the highlighter to call out your state's flagship. On this chart, 50 (at the top) is the highest rate; 1 (at the bottom) is the lowest.
View two is a map to see relative values: Here, purple is low, and orange is high. Choose a year, then choose a value to display: Resident tuition, non-resident tuition; non-resident premium (how much more a non-resident pays), and non-resident percent (that premium as a function of the resident rate.)
View three is a single institution over time, showing your choice of inflation-adjusted dollars to 2020, or nominal (unadjusted) dollars.
And view four also shows a single institution, but percentage change.
Enjoy, and as always, let me know what you find that's interesting.
