Notes: RSE = robust standard errors. In addition to the indicators shown, all regressions control for age at time of interview, school status, urban/rural residence, and economic status at time of interview. Comparison categories are in parentheses. Age is centered on 8, referencing the first age represented in the life history calendar.
