Extinction of a Line of Descent

Abstract

The reasoning by which we have arrived at the notion and measure of the intrinsic rate of increase of the population is based on the general fertility function m(a).In consequence, our conclusions represent the mean, the collective result as it presents itself in a population taken as a whole. The functions of fertility by the order of the child m n (a) that we have just introduced permit us to push our analysis further. The average rate of increase r does not apply equally to any element of the population taken randomly, for example to the descendants in a direct line (carrying the same family name) of some individual.
