A landmark 1995 study showed that how fast children's vocabularies grow is greatly influenced by how often their parents talk to them — and that children from lower-income families hear significantly fewer words than their wealthier counterparts.
The study found that, in a year, children of professionals hear 11 million words on average, while children of working-class families hear 6 million words, and children of families on public assistance hear 3 million words.
