What difference does it make?
Children growing up in homes with at least twenty books get three years more schooling than children from bookless homes, independent of their parents’ education, occupation, and class.
Children from lower-income homes have limited access to books. Because of this, preschoolers from low-income families have fewer home and preschool language and literacy opportunities than children from economically advantaged backgrounds – a major reason that they lag behind in reading achievement throughout the school years.
Children who aren’t reading at grade level by the end of third grade are four times as likely to drop out of high school.
35 million U.S. adults have reading skills below a fourth-grade level. That's 1 in 6 U.S. adults.
