Chapter 12: Interpreting the Tables and Graphs
gross per capita consumption. This graph is a direct representation of the progressivity of health payments. These are progressive if their share of household consumption increases with consumption and are regressive in the opposite case. Finally, if their budget share does not vary with consumption, health payments are proportional to income. Interpreting the Results Our example shows that out-of-pocket payments are progressive over the first three quintiles, then stabilize, and finally become regressive for the richest quintile.
Note 1. This interpretation is discussed in technical note 18 in chapter 13.
