- DiogenesKynikos 6y ago350,000 cases/year * 32 years = 11.2 million cases, which is in the right ballpark, assuming we're counting from 1988.
- gus_massa 6y ago350,000 cases/year * 32 years = 11.2 million cases They may have some more precise method, but with this estimation 11 or 13 millions doesn't seams to be too off.
