Life expectancy is how long people in a certain country or area are expected to live. EX: The life expectancy of people in Australia is 82.10 years as of 2012. That means most people live for around 82 years in Australia. The life expectancy of people in Ethiopia is approximately 62 years. Disease, vaccines, available food, clean water, genetics, and infant mortality are all things that affect life expectancy.
