Data source: Joint Canada/United States Survey of Health (JCUSH).
HUI: Health Utilities Index.
Expected mean difference in HUI between two randomly selected persons in the population is twice the value of the Gini coefficient of the mean HUI.
Analysis is weighted. Standard errors are adjusted for the complex survey design.
The mean HUIs for the three distributions above are the same without weighting (data not shown) but different after weighting as seen above.
