Tips before you play
- Across all 199 countries in 2024, rates run from 2.4% to 75.9%.
- The middle country (the median) sits at about 22.3% — a good starting guess if you have no idea.
- All answers are WHO estimates for adults aged 18 and over, age-standardized so countries can be compared fairly.
