Measuring Distributional Inequality: Relative Body Mass Index Distributions by Gender, Race/Ethnicity, and Education, United States (1999–2006)

Figure 2

Decomposing relative body mass index distributions (1999–2006) between non-Hispanic Black and White men (top) and women (bottom) into impact of changes in medians and changes in shape. (a,d) Unadjusted relative body mass index density; (b,e) effect of median difference in body mass index between race/ethnic subgroup; (c,f) median-adjusted relative body mass index density. Deciles chart superimposed on relative densities. Data from the National Health and Nutrition Examination Survey.
