College degrees in mid-20th Century U.S.A.

What percentage of the adult U.S. population held a college degree in 1940? How does that compare to today?

I don’t have the figures, but the percentage was far less in 1940. It wasn’t until the GI Bill after WWII that a college education began to become universal.

From the U.S. Census Bureau: 5% of Americans age 25 or older had a bachelor’s degree in 1940. That rose to 20% by 1990. Also:

I should have written: 5% had a bachelor’s degree or higher.

I was aware of the effect of the G.I. Bill; that’s how my father wound up going to college. In fact it was my thinking about some of the jobs he had before the war without having a degree that lead to the question. I’d imagine nowadays it would be difficult to even be considered as a hospital business director without something like a Masters in Public Healllth or some such.

Thanks for the numbers, Walloon.
