A recent study published in BMC Geriatrics sought to “estimate the associations between survival probability of becoming a centenarian (SPBC) for those aged 70, and the gross national income, health expenditure, telecommunications, and sanitation facilities in 32 countries.” Data for this study was obtained from the United Nations Development Programme and the Human Mortality Database. The authors found a significant positive correlation between SPBC and the socioeconomic levels in all 32 countries. The study identified “higher overall economic development level, public expenditure on health, mobile telephone subscribers are standard of living, and the use of improved sanitation facilities,” as four important aspects of socioeconomic indicators in the SPBC for those aged 70.
