Standard & Poor's Global Financial Survey uses four questions to test basic numeracy and understanding of interest compounding, inflation, and risk diversification.

(we won't judge too hard if you get one wrong).
In major emerging economies, it’s the 15- to 35-year-old demographic that shows the highest percentage of financial literacy. In major advanced economies, that distinction goes to the 36- to 50-year-old crowbd.
