Here’s an article from January of this year, outlining the decline of reading in the US, and how the worst may be over.
In 2013, 23% of American adults did not read a single book.
The average American read 5 books last year, with women reading 50% more than men.
While the percentage of Americans who did not read a single book has tripled since the late ’70s, the percentage of young Americans (aged 18-24) who read at least one book for pleasure in the past year has been holding steady for the past ten years, ending what had been a steady decline.
Finally, the Americans who read the most are those who have completed college, and those who have the highest incomes; both groups read nearly twice as much as the average American.
