Height for Age Z-Score (HAZ) by Village and Ethnicity.

Village means arranged in descending order, with 95% confidence intervals. Ethnicity is coded as the most common ethnicity in each village (see File S1 for details). Children in Maasai majority villages tend to have relatively low HAZ scores and children in Meru majority villages tend to have relatively high HAZ scores, with Sukuma and Rangi majority villages intermediate between these extremes. Red circle  =  Maasai village; orange triangle  =  Rangi village; green diamond  =  Sukuma village; blue square  =  Meru village; white diamond  =  Other ethnicity village. HAZ scores falling below <2 are categorized as “stunted” by the World Health Organization.
