An Estimate of the Degrees of the Mortality of Mankind

  • Edmund Halley
Part of the Biomathematics book series (BIOMATHEMATICS, volume 6)


Halley’s text may be clearer if the reader notes that he intends: l 0 = 1238; L 0 = 1000; l 1 = 890; L 1 = 855. According to Westergaard (1969, p. 34) the Breslau lists showed 1218 births in 1691, among whom 992 were alive on January 1, 1692. Rounding the figure, Halley set L 0 = 1000 for 1238 births.
