A study (Australian National University and University of Nevada) found that having more books growing up, even if you don’t read them, improves educational outcomes. The study found strong correlations between the number of books owned at age 16 and later-in-life literacy, math, and IT skills. The households with the most books are in Estonia, with an average of 218 books per house. Norway came in second with an average of 212 books per house. The US doesn’t crack the top ten.
