Middle-class children get 1,000–1,700 hours of one-on-one reading, while low-income children average only 25 hours.
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.
