No data on stunting, age and household SES is presented for the initial sample due to a high number of missing values. The share of children living in households of each SES quartile differs from 25% as birth rates tend to be higher in low SES households and ties in household asset scores can occur.
“n/a” = not applicable (statistics on stunting, child age and household SES not calculated in initial sample due to missing values)
SES, socioeconomic status.
