Leading source of global health data

In 1950, the average human lived 47 years. Today, it's 73. The global age-standardized mortality rate has dropped 67% over that span—driven not by a single breakthrough but by the compounding effects of vaccines, clean water, antibiotics, and basic sanitation reaching billions of people who previously lacked access. Lower respiratory infections (LRIs)—once the leading cause of infectious disease death—killed 2.5 million people in 2023, down 33% among children under five since 2010.
