Which country has the lowest infant mortality rate?

Monaco has the lowest infant mortality rate among the countries listed. This is significant as infant mortality rate is a key indicator of overall health in a country, reflecting the effectiveness of health care systems, maternal care, and public health policies. Monaco, a small city-state with a highly developed healthcare system, benefits from advanced medical technology and high standards of living, which contribute to its exceptionally low rates of infant mortality.

In contrast, while Japan, Sweden, and Norway are also recognized for their highly developed healthcare systems and low infant mortality rates, Monaco stands out due to its unique combination of wealth, health resources, and population characteristics that create optimal conditions for infant health and survival. Therefore, understanding the context of healthcare infrastructure and societal factors allows us to appreciate why Monaco currently leads in this critical health metric.
