Women Live Longer Than Men in Almost Every Country on Earth

Women outlive men by an average of 4–6 years globally, a gap observed in nearly every country in the world. In Japan, average female life expectancy exceeds 87 years. Scientists point to biological factors including two X chromosomes (which may buffer genetic defects), higher estrogen levels that protect cardiovascular health, and lower rates of risk-taking behavior. Social factors such as lower rates of smoking and alcohol consumption also contribute.
