Resumen
La mortalidad es uno de los componentes de la dinámica demográfica constituido en un importante
indicador del reflejo del estado de salud de una población, por lo que conocer su comportamiento es de
suma importancia en el desarrollo de las sociedades. El objetivo de la presente investigación es construir
un modelo de análisis factorial mediante la aplicación de la técnica de componentes principales a un
conjunto de tasas de mortalidad por grupo de edad y sexo para identificar componentes influyentes en la
mortalidad de Costa Rica durante el período 1900-2010. El análisis factorial permitió identificar
inicialmente tres factores principales que explican en un 96,6 % la variabilidad de la mortalidad de Costa
Rica. Se espera que esta serie de estimaciones contribuyan al estudio del comportamiento de la mortalidad
y de sus implicaciones para el desarrollo del país y, a su vez, sirva de base para que futuros estudios
complementen los alcances de la presente investigación.
The mortality is one of the components of the demographic dynamics constituted as an essential pointer of a population’s health status reflection, that’s why it is extremely important for the societies’ development to know about its behavior. The objective of the current investigation is to build a factor analysis model by applying the technique of main components to a death rate set, according to age and gender groups, in order to identify influential components in Costa Rica’s mortality between 1900 and 2010. The factor analysis allowed us to initially identify three main factors which show in a 96,6 % the variability in Costa Rica’s mortality. It is expected from these estimates to contribute with the study of mortality, its behaviors and implications for the development of the country. At the same time, these estimates are expected to work as a base, with the purpose of complementing further studies with the achievements of this research.
