The circumstances you grow up in are linked to how long you live

Research shows a significant gap in life expectancy between the richest and poorest individuals in wealthy countries. In Norway, a 40-year-old man in the top 1% can expect to live nearly 14 years longer than one in the bottom 1%. In the U.S., the gap is nearly 15 years. The World Health Organization warned in 2025 that international targets for reducing health inequalities may not be met.
