From a Wall Street Journal story by Simon Constable headlined “Five Books to Make You Smarter About Money”:

A troubling number of Americans lack financial literacy. It’s an issue across all generations, but especially among young adults.

U.S. adults on average got 48% of the questions correct on the 2023 Personal Finance Index survey by TIAA Institute and the Global Financial Literacy Excellence Center, which measures knowledge of personal-finance topics. The results for Gen Z, the generation born from 1997 to 2012, were even worse, coming in at only 38%.
