evidence: Global life expectancy to increase by nearly 5 years by 2050 despite geopolitical, metabolic, and environmental threats, reports new global study [...] As the disease burden continues to shift from CMNNs to NCDs and from years of life lost (YLLs) to years lived with disability (YLDs), more people are expected to live longer, but with more years spent in poor health. Global life expectancy is forecasted to increase from 73.6 years of age in 2022 to 78.1 years of age in 2050 (a 4.5-year increase). Global healthy life expectancy (HALE) – the average number of years a person can expect to live in good health – will increase from 64.8 years in 2022 to 67.4 years in 2050 (a 2.6-year increase). [...] To come to these conclusions, the study forecasts cause-specific mortality; YLLs; YLDs; disability-adjusted life years (DALYs, or lost years of healthy life due to poor health and early death); life expectancy; and HALE from 2022 through 2050 for 204 countries and territories.
