Children’s vocabulary skills are linked to their economic backgrounds. A research by Stanford University shows that “by 3 years of age, there is a 30 million word gap between children from the wealthiest and poorest families. A recent study shows that the vocabulary gap is evident in toddlers. By 18 months, children in different socio-economic groups display dramatic differences in their vocabularies. By 2 years, the disparity in vocabulary development has grown significantly”.
