Socioeconomic Determinants of Health and Longevity
Quick fact
Life expectancy and health improve step by step with each increase in income, education, or social rank—a 'social gradient' that runs from the top to the bottom of society. For example, in many countries, the richest live 5–10 years longer than the poorest, and this difference is not just between rich and poor but between every rung of the ladder.
Why this is interesting
You probably think that good health comes down to good genes and healthy habits—but what if your income and education were just as important?
