Accepted Answer

Monaco achieves a world-leading life expectancy of 86.5 years largely due to its high standard of living, exceptional healthcare system, and wealthy demographic. As a highly developed microstate, it lacks rural poverty and provides its citizens with excellent access to nutritional and medical resources. These socio-economic advantages combine to push its average lifespan well above the global average of 73.32 years.
