This study introduces a difference-in-decompositions approach to show that although 19th century African American current net nutrition was comparable to working-class Whites, it was made worse-off with the transition to free-labor. BMI reflects net nutrition over the life-course, and like stature, slave children¡¯s BMIs increased more than Whites as they approached entry into the adult slave labor force. Agricultural worker¡¯s net nutrition was better than workers in other occupations but was worse-off under free-labor and industrialization. Within-group BMI variation was greater than across-group variation, and White within-group variation associated with socioeconomic status was greater than African Americans %K BMI variation %K current net nutrition %K Oaxaca decomposition %U https://journals.sagepub.com/doi/full/10.1177/0034644618820928
