In 2015, the global population’s average life expectancy — which reflects the overall mortality level of a population — was 71.4 years old, according to the World Health Organization. Factors that affect the age you’re expected to achieve include the region’s diseases, mental health, substance abuse, violence, nutrition, drinking water, road traffic injuries, sexual and reproductive health, environmental pollution, vaccines, and more.

Gender also plays a major role in lifespan; women last year were expected to live around 73 years, but for men around the world it was only 69.1 years. In the Americas, females lived an average 79.9 years, but males had an average life expectancy of 74.

Out of 224 countries listed on the CIA’s World Factbook, the United States comes in at 43rd, with a life expectancy of 79.68 years. What’s the highest life expectancy? In 2015, citizens of Monaco hit an average age of 89.52 years. How do other countries around the world stack up?
