Infant mortality can significantly impact which of the following?

Infant mortality has a significant impact on overall life expectancy because it directly influences the average lifespan of a population. High rates of infant mortality can lower the average life expectancy, as the deaths of infants contribute to a lower average age at death when calculated across the entire population. This measure indicates the health and wellbeing of a society, and high infant mortality rates are often associated with inadequate healthcare, poor maternal health, and inadequate nutrition, all of which contribute to reduced life expectancy.

In contrast, while infant mortality may relate to national GDP, healthcare access, and quality of education, the most direct and clear connection is with overall life expectancy. By examining life expectancy, one can understand the broader implications of infant mortality on societal health and development. High infant mortality rates can signal deeper systemic issues affecting the entire population's health, emphasizing the need for comprehensive healthcare and social support systems to improve outcomes for future generations.
