Analysis of Age-Structure Models

Begin by developing a mathematical model for the growth of a population. Assume that the population is closed to migration, and that only the females are counted. Males are present for reproductive purposes, but are not specifically taken into consideration. In the case of human and other higher species, this makes sense for two reasons. Females know unequivocally who their offspring are; and (more importantly for the purposes of this model) females have a biologically well-defined beginning and end to their reproductive careers.
