> Between 2006-07 and 2019-20, COA [cost of attendance] increased by around 27% at both types of institutions, but declined by 7-8% in the few years after that. The recent decline occurred because colleges posted similar nominal COA increases as in the past, but inflation was higher. Overall, COA increased by almost 20% over those 16 years at both types of institutions.
> But average net prices rose at a considerably more modest pace. Between 2006-07 and 2019-20, average net price increased by 13% and 7% at public and private four-year institutions, respectively. Those increases reversed in the post-COVID years. Overall, average net prices are largely unchanged, adjusted for inflation, compared to 2006-07.
