Most language inequality for infants begins very early in their development. For most, this disparity develops prior to 36 months (Farkus & Baron, 2000).
• Significant disparities in vocabulary size between socioeconomic status (SES) were evident by 18 months. By 24 months, there was a 6 month age gap (Fernald et al, 2011).
• 65% of low SES preschoolers in head start programs had clinically significant language delays (Ramey and Ramey, 2004)
• Maternal education is a known indicator of SES and is correlated with language input for infants (Dollaghan et al. 1999).
• At 18 months, most infants experience “word spurts” and an increase in expressive vocabulary (Reznick & Goldfield, 1992).
