Figure 1

BMI density by KGBV cohorts.Notes: The figure plots the density of BMI values. The area between the two vertical lines is the potential healthy zone, i.e., BMI between 18.5 and 25. The panel on the right plots the densities for the affected cohort, i.e., girls of lower castes in the affected age cohort, and the left-hand side panel includes everyone else.
