A population in which age-specific fertility and mortality are assumed to be constant and to and from which no migration takes place. The concept was first developed in a series of papers by Alfred Lotka (see, for example, Lotka, 1922) and is much used in demographic analysis. He showed how such a population tends towards a constant age distribution which increases at a constant rate. A stationary population, a special case of a stable population, is one where fertility and mortality are equal and the age distribution is the life table distribution. (PEO)
