An Estimate of the Degrees of the Mortality of MankindHalley’s text may be clearer if the reader notes that he intends: .. = 1238; .. = 1000; .. = 890; .. = 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 .. = 1000 for 1238 births.

A General Investigation into the Mortality and Multiplication of the Human SpeciesEuler’s virtually unknown article, published by the Belgian Académie Royale des Sciences et Belles-Lettres in 1760, anticipates important parts of modern stable population theory for a one-sex population closed to migration. Its ideas have been published many times during the subsequent two centuries by writers who independently rediscovered them.
