Yes, good point.
I wanted to add that the average debt number in the TICA report ($29,200) is only for the subset of undergrads who took any debt (65%). So, about 1/3 of students had no debt, which obviously would drive the average debt number down if looking at the entire class of 2018.
I am not sure I’ve heard someone argue that 48% is too high a proportion of 25+ year olds having a bachelor’s degree. I am open to hearing that reasoning though.
