The measurement of Darwinian fitness in human populations
Abstract
Darwinian fitness of a biological trait refers to the contribution to successive generations made by individuals possessing the trait. This contribution depends on the age-specific fecundity and mortality of the individuals in the population. This paper gives, for human populations, an empirical study of two measures of Darwinian fitness: the Malthusian parameter, which describes the rate of increase of the actual population size, and entropy which describes the rate of increase of the effective population size. This empirical study indicates that Darwinian fitness is measured by entropy. This finding is in accord with the predictions of recent theoretical studies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
