Interpolation of cubic splines for estimates in the development of mortality tables for Honduras

Abstract

The basic tool for the quantitative study of survival is known as mortality table or life table. Mortality tables are a theoretical model of mortality experienced by a hypothetical cohort of those born on the same date, from the initial moment of birth until the complete extinction of the cohort by the exclusive action of mortality. Life tables are essential for determining the reserves for pensions and the resources required to preserve the basic principle of financial stability in the medium and long term. The method presented in this research is not intended to replace conventional ways for mortality tables, it's just to make estimates when enough information is not available in normal ways. But it is expected on the short term that the country will take awareness on the importance of life tables and work with organizations to collect adequate information and to prepare them in the conventional way. If governments really want to encourage social improvement, for people at retirement age, appropriate life tables should be developed to guarantee the system´s stability.
