Abstract

En este trabajo se aplica el método de Lee-Carter para proyectar la mortalidad de México. Dicho método supone una relación lineal entre el logaritmo natural de las tasas centrales de mortalidad y la edad y el tiempo; una de sus ventajas es que es parsimonioso, pues combina un modelo demográfico con pocos supuestos con el análisis de series de tiempo; otra ventaja es que es posible medir la incertidumbre asociada al evento mortalidad y así calcular intervalos de confianza. Los pronósticos de la esperanza de vida al nacer de la población femenina para 2050 prevén con un 95% de confianza que podría variar entre 83.53 y 86.40 años, y en el caso de los hombres oscilaría entre 78.53 y 80.53 años. AbstractThis study uses the Lee-Carter method to project mortality in Mexico. This method assumes a linear connection between the natural logarithm of the central rates of mortality and age and time. One of its advantages is that it is parsimonious, since it combines a demographic model with few assumptions with the analysis of time series. Another advantage is that it is possible to measure the uncertainty associated with the mortality event and thus calculate confidence intervals. The forecast of life expectancy at birth for female population to 2050 foresee, with 95% of confidence that it could vary between 83.53 and 86.40 years and in the case of men, would oscillate between 78.53 and 80.53 years.
