What Is Human Life Expectancy?
Human life expectancy is the average number of years a newborn is expected to live under current mortality conditions. It is a standard measure of population health and is commonly reported by national statistics agencies and global health organizations.
Global Trends and Recent Data
Global average life expectancy has risen for decades due to improvements in sanitation, nutrition, and medical care. According to the World Health Organization, recent estimates place global life expectancy at around 73 years, though progress has slowed in some regions.
Key Factors That Influence Life Expectancy
Major factors include access to healthcare, disease prevalence, income levels, education, and lifestyle behaviors such as diet and physical activity. Public health investments and reductions in child mortality have historically driven the largest gains in life expectancy.
