In 1662, John Graunt, a London merchant, published the first set of actuarial tables in his book Observations on the Bills of Mortality. Graunt provides many interesting statistics regarding causes of deaths in London in 1632. Seven people are listed as being murdered, 10 people as having died from cancer, and no specific mention is made of heart ailments. On the other hand, 13 people are listed as having died from "planet", 38 from "king's evil", and 98 from "rising of the lights". Possibly the saddest statistic, however, is that out of 9,535 deaths that year, infants made up 2,268 of them, over 23%. (source)
