Average Life Expectancy By Country
What is life expectancy?
Average life expectancy defines the average amount of years a person may live, based on the year of his birth, his current age and other demographic factors if mortality at each age remains constant in the future. The most commonly used indicator is life expectancy at birth – the expectancy of life for individual at age zero.
Life expectancy is one of the key factors which influence the country population dynamics.
Life expectancy at birth summarize mortality at all ages. On this reason it can both grow or decrease as far as a person becomes older depending on specific of each case.
For example it is well known fact that life expectancy at birth was extremely low in Medieval Europe – nearly 30 years. But for people who reached 21 it increased up to 64 (additional 43 years).
How did it happened? This case explained by very high infant mortality rate. The child who was just born had a big chance (nearly 50%) do die during next 15 years. But as far as you reach 21 you can have a good change to stay alive till 60.

What life expectancy at birth tell us about?
Life expectancy at birth is also a measure of overall quality of life in a country and summarizes the mortality at all ages. Than more comfortable and safety society is than (usually) higher life expectancy at birth.
Following factors push life expectancy at birth down (negative effects):
- infant mortality
- criminal mortality
- bad nutrition
- unavailable medicare
- environmental problem (dirty air, water, radiation etc.)
All this factors aggregate influence of economics, environment quality, crime and a lot of other factors. Therefore life expectancy at birth is a very important factor which tells you a lot about quality of life in the country.
