Fries in his compression of morbidity theory proposed that decline in premature deaths and postponement of chronic illness leads to a more rectangle shaped survival curve, concentrating diseases and death at the end of life (mortality compression). This study results show signs of mortality compression with a gradual concentration of deaths around the modal age and a rectangularization of the survival curve in Chileans between 1969-2002. However, mortality is not only being compressed but also moving towards the right since modal age of death has increased, meaning that "most common length of life" in Chile is increasing.
