The 30 Million Word Gap

Father-and-sonIt all began with the 1995 landmark study by Betty Hart and Todd R. Risley in their book Meaningful Differences in the Everyday Experience of Young American Children:

“In four years, an average child in a professional family would accumulate experience with almost 45 million words, an average child in a working-class family 26 million words, and an average child in a welfare family 13 million words.”

More recently, Stanford University researchers have observed that these differences emerge as early as 18 months. The effects persist through the school years. The good news: if parents increase the quantity and quality of their verbal interactions, their babies benefit. Many organizations are tackling the issue and resources are developing all the time.
