These population weights are race-specific averages of males' and females' population distributions of the variable, adjusted for Add Health's clustered sampling design and unequal probability of selection.
These decomposition estimates (from the modified Kitagawa decomposition technique) divide the overall female-male disparity into stratum-specific components. Because of rounding, the components may not add up to the total female-male disparity (all values in this column).
These decomposition estimates (from modified Kitagawa decomposition) express the stratum-specific components of the female-male disparity as percentages of the sum of the absolute values of the stratum-specific components of the female-male disparity (all values in this column).
