Measuring the concentration of economic-burden outcomes in a birth cohort. The data represent information about 940 people who were born in one hospital in 1972-73 and are life-long participants in the Dunedin Longitudinal Study. The panels show that a minority of individuals accounts for a majority of outcomes in a birth cohort, in each of 8 different social and health sectors: social welfare (Panel A), fatherless children (Panel B), smoking (Panel C), excess obese kilograms (Panel D), hospital stays (Panel E), prescription fills (Panel F), injury claims (Panel G), and crime (Panel H). Each Panel displays the cumulative distribution of an outcome in the cohort. To find the proportion of each outcome that 20% of the population accounts for, start at 20% on the vertical axis and follow arrow 1 to the right, to the purple line; then, follow arrow 2 up to the blue line; and then follow arrow 3 to the left, back to the vertical axis to find the corresponding proportion of the total.
