Literacy skills

Found this in the new 70-page PDF from the Harvard Business School Survey on U.S. Competitiveness, Problems Unsolved and a Nation Divided:

Younger cohorts of U.S. workers have higher literacy scores than older cohorts in absolute terms, reflecting U.S. skills improvement over time. But workers elsewhere have improved even faster. American workers from earlier generations are more literate than their international peers of the same age, but younger U.S. workers are less literate than their peers.

Younger Americans are more literate than older Americans? That depends on your standard of literacy.
