La deriva de la longevidad

This work provides additional data that enables us to understand the magnitude of the challenge to Spanish society, which, according to an OECD report, in 2050 will have 77 retirees for every 100 citizens of working age. For this reason, the latest projections of longevity improvements are analysed from the population demography, to define prospective scenarios of population structures in order to understand social inequities, which result in survival records not being homogeneous in plural societies of the 21st century. In conclusion, he points out that the phenomenon of increased longevity presents a set of uncertainties, despite the slowdown in this decade, which makes it difficult to construct actuarial models for estimating the trend of statistically robust medium-long term survival improvements. In addition, the aging economy must be the instrument that guarantees an intergenerational and intragenerational social pact, based on dignified old age, in any of the three stages: active retirees (the sixties), slower retirees (the seventies), needy retirees (eighty onwards). This arbitrary and chronological classification should be reformulated, following biological senescence parameters that would accurately measure the fragility associated with aging.
