What Is Life Expectancy?
Life Expectancy is the statistical expectation of how long someone will live at birth based on a number of factors such as socioeconomics, demographic, geographics, thermographic, stenographic, idiographic, and historiographics.
To answer the question of ‘What is life expectancy?’ let’s look to an example:
When you are born, based on a number of factors I’m not really sure I understand, people with fancy math degrees create an algorithm that can determine the average lifespan.
Of course, if you look at each person individually, the number will rarely be accurate because it adds everyone up together to get an average.
That means many people will die before the number and many people will die after the number but when added together, that will give you the average life expectancy.
