Research shows a strong, positive association between home reading environment, access to books, frequency of reading, and variety of books read and brain activation during story listening.

Children who do not read on grade-level by the end of third grade are four times less likely to graduate high school on time.

In a research study of 42 countries, the quantity of books in homes was the second most important predictor of reading performance. In fact, having about 100 books in the home yielded a reading performance 1.5 years higher than those with fewer books.
