Life expectancy is a statistical calculation whose What is life  definition is shared by all national and international organizations? starting with the United Nations (UN). Life expectancy at birth measured for a given year is “the average lifespan of a fictitious generation that would experience? throughout its existence? the age-specific mortality conditions of the year in question. It is a synthetic indicator of the age-specific mortality rates of the year in question.” But what does this mean in concrete terms?

What is the point? if it is “fictitious

To understand what life expectancy at birth is? the easiest way is to take an example. In 2019? before the Covid-19 pandemic? life expectancy at birth for women was 85.6 years and for men was 79.7 years.  at which malta phone number library women and men would have died if they had had? throughout their lives? the mortality rates by sex and age observed in 2019.

To illustrate how life expectancy in 2019 is calculated? let’s follow the flow below:

Let’s start with a population of 100 people born in this approach is particularly useful 2019. Let’s assume that these people are subject throughout their lives to the “mortality conditions” of the year 2019? that is to say that they have at each age the mortality rates by sex and age observed in 2019.

We calculate? under these conditions? how many people would die before their 1st birthday ; to do this? we apply to these 100 babies the probability that they die before the age of 1? observed in 2019. Let N1 be the number of babies who died before the age of 1.

This is the average age

We then calculate how many people would die germany cell number before their 2nd birthday ; to do this? we apply to these 100-N1 people the probability that they die between the ages of 1 and 2? observed in 2019. Let N2 be the number of people who died between the ages of 1 and 2.
