RT Journal Article SR Electronic T1 The Socioeconomic Gradient of Child Development: Cross-Sectional Evidence from Children 6–42 Months in Bogota JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 464 OP 483 DO 10.3368/jhr.50.2.464 VO 50 IS 2 A1 Marta Rubio-Codina A1 Orazio Attanasio A1 Costas Meghir A1 Natalia Varela A1 Sally Grantham-McGregor YR 2015 UL http://jhr.uwpress.org/content/50/2/464.abstract AB We study the socioeconomic gradient of child development on a sample of low- and middle-income children aged 6–42 months in Bogota using the Bayley Scales of Infant and Toddler Development. We find an average difference of 0.53, 0.42, and 0.49 standard deviations (SD) in cognition, receptive, and expressive language respectively, between children in the top and bottom quartile of the wealth distribution. These gaps increase substantially to 0.81 SD (cognition), 0.76 SD (receptive language), and 0.68 SD (expressive language) for children aged 31–42 months. These robust findings can inform the design and targeting of interventions promoting early childhood development.
