Note: N = 3288 for 1996/97 and 3884 for 2014. OLS regression. Standard errors used take into account sampling weights. In addition to the variables reported, all regressions control for division-specific fixed effects. Antenatal visit to doctor, delivery at health facility, early breastfeeding, and maternal CED and short stature are all dummy variables
