Rising caloric intake and incomes contributed to the earliest gains, while later improvements stemmed from public health developments, including updated modern sanitation systems, vaccination, and antibiotics. However, not all populations improved in health equally. Life expectancy rose much more in high-income countries than in low-income ones, and within countries, more so for the high-income than low-income individuals. Even within countries with low average mortality risk, factors such as income, education, and race predict how long an individual will live.</style></abstract></record></records></xml>
