 Resumen:

One of the foremost problems in formal demography has been including information on the vital rates from both males and females in models of population renewal and growth, the so-called two-sex problem. The two-sex problem can be conceived as a subset of the analytical problems entailed by multigroup population modeling. This dissertation characterizes the two-sex problem by means of decomposing the vital rate components to the sex-gap between the male and female single-sex stable growth rates. A suite of two-sex models for age-structured models from the literature are presented in a standard reproducible format. A new variety of age-structure, age based on remaining years of life, is presented. Analogous models of population growth for the single-sex and two-sex cases are developed for populations structured by remaining years of life. It is found that populations structured by remaining years of life produce less sex-divergence than age-structured models, thereby reducing some of the trade-offs inherent in two-sex modeling decisions. In general, populations structured by remaining years are found to be more stable over time and closer to their ultimate model stable structures than age-structured populations. Models of population growth based on remaining-years structure are found to diverge from like-designed age-structured models. This divergence is characterized in terms of the two-sex problem and we call it to two-age problem.
