Population momentum is a consequence of the demographic transition.Population momentum explains why a population will continue to grow even if the fertility rate declines. Practice: Identifying the population and sample. ‘For instance, fertility inheritance in a stationary population will, in some aspects, affect the coalescent tree in a similar way as population growth.’ ‘It is based on the probability of having a number of alleles greater or equal to the observed number in sample drawn from a stationary population.’ These pyramids show a strong base and a very narrow top. Stationary populations (revision) See PAPP101_S08 for an overview of a stationary population.
