Notes: Robust standard errors in parentheses (*** p<0.01, ** p<0.05, * p<0.1), clustered at the level of DHS cluster (primary sampling unit). Treatment exposure calculated using month and year of birth, and years in which the program was rolled out in each district (see Table A1). Specifications also control for: district fixed effects; urban dummy; rainy season dummy; percent of household's salt that is iodized (0, 25, 50, 75, or 100); minimum and maximum sibling ages; dummies for median sibling age; household size (deciles); number of females in household (quintiles); gender-specific birth order dummies; dummies for number of younger and older siblings; dummies for mother's integer age; and dummies for mother's years of completed schooling. Sample is restricted to households with at least 1 child < 5 years in 1999 DHS.
