A prevalence rises from 58.6% to 67.1%. What is the percentage-point increase?

8.5 points. Subtract the percentages: 67.1 − 58.6 = 8.5 percentage points. The two original percentages are not the change. About 14.5% would be the relative percentage increase after dividing by 58.6. Percentage points and relative percentage change differ.

Which example is food fortification rather than separate supplementation?
