Scatterplots showing relationships among selected measures of the length of life and lifespan equality for the 12 datasets analyzed. A–C show scatterplots between measures of length of life, D–F show comparisons between measures of lifespan equality, and G–I show scatterplots between length of life and measures of lifespan equality. For display purposes, the values of the Gini coefficient and the coefficient of variation were transformed by subtracting each population’s value from the maximum in the dataset.
