[Robust estimation of fertility by the use of model stable populations]. / Estimacion robusta de la fecundidad mediante el empleo de modelos de poblaciones estables

"If we know the proportion of population under 15 years of age, the probability of newborns to reach 5 years of age and the rate of growth of that population, by means of a very simple procedure we can estimate the birth rate, the growth reproduction rate and the total fertility rate through the appropriate use of stable population models. Even if the real population is far from being a stable population the estimates are very little affected, which shows the robustness of the procedure." (summary in ENG)
