| Summary: | Longitudinal patterns of child
development and socioeconomic status are described for a
cohort of children in Madagascar who were surveyed when they
were 3–6 and 7-10 years old. Substantial wealth gradients
were found across multiple domains: receptive vocabulary,
cognition, sustained attention, and working memory. The
results are robust to the inclusion of lagged outcomes,
maternal endowments, measures of child health, and home
stimulation. Wealth gradients are significant at ages 3–4,
widen with age, and flatten out by ages 9-10. For vocabulary
and sustained attention, the gradient grows steadily between
ages three and six; for cognitive composite and memory of
phrases, the gradient widens later (ages 7-8) before
flattening out. These gaps in cognitive outcomes translate
into equally sizeable gaps in learning outcomes. Between 12
and 18 percent of the predicted gap in early outcomes is
accounted for by differences in home stimulation, even after
controlling for maternal education and endowments. |
