In middle-income neighborhoods the ratio of books per child is 13 to 1, in low-income neighborhoods, the ratio is 1 age-appropriate book for every 300 children. Neuman, Susan B. and David K. Dickinson, ed. Handbook of Early Literacy Research, Volume 2. New York, NY: 2006, p. 31
61% of low-income families have no books at all in their homes for their children. Reading Literacy in the United States: Findings from the IEA Reading Literacy Study. (1996).
Children in low-income families lack essential one-on-one reading time. The average child growing up in a middle class family has been exposed to 1,000 to 1,700 hours of one-on-one picture book reading. The average child growing up in a low-income family, in contrast, has only been exposed to 25 hours of one-on-one reading. McQuillan, J. (1998).The Literacy Crisis: False Claims, Real Solutions.
