Notes: Robust standard errors in parentheses clustered at the ward level.

Control mean in the final row represents the mean level of the control group for the relevant outcome. Coefficients estimated using a linear probability model including block fixed effects. Indices represent the average normalized z-score across variables used in each set (sanitation, hygiene, health), weighted by the inverse of the design effect resulting from the unique intracluster correlation for each variable. Variables that are collected at a level different to the household are not included in the sanitation or hygiene index. The same holds for health variables not collected at the child level.
