The question is underspecified:Do you mean:people dying of plague as a percentage of the total population?people dying from the plague as a percentage of people dying from all causes?In either case, it would also be helpful to know where and when.I would suggest that on Antarctica, in the sixth century, the percentage of people dying from plague was zero!
