It's the total for both males and females for that type of self-reported physical or sexual abuse. The first set of three bars, the dark blue, would be the prevalence of physical abuse for females, and that is a bit above 20%. The physical abuse for males would be higher, at more than 30%, but when you combine both boys and girls, it would make about 26%.
