Which statement explains why infant mortality and life expectancy are key determinants in health rankings?

• A. They summarize population health and health system performance
• B. They measure only genetic factors
• C. They reflect only access to hospitals
• D. They are not used in rankings

Answer: (A)

Understanding health rankings relies on outcome indicators that capture both how healthy a population is and how well the health system functions. Infant mortality and life expectancy fit this because they reflect broad aspects of health and care. Infant mortality measures deaths before age one and is highly sensitive to maternal health, prenatal and postnatal care, nutrition, vaccination, disease prevention, and the effectiveness of public health and healthcare services. Life expectancy looks at how long people live on average, integrating the impact of chronic and acute diseases, injuries, access to care, quality of care, and social and economic conditions across the lifespan. Together, they summarize the overall health status of a population and how well its health system supports that health, making them powerful, comparable indicators for rankings. They aren’t limited to genetic factors and aren’t driven only by access to hospitals; they reflect a wide range of social, economic, and health system determinants. That combination is why these measures are central in health rankings.
