Everywhere in the world women live longer than men — but this was not always the case. The available data from rich countries shows that women didn’t live longer than men in the 19th century. Why do women live much longer than men today and Hackfabmake.space/index.php/Utilisateur:TeddyDettmann6 (mouse click on kids4drugfree.net) why have these advantages gotten bigger over time? We have only a small amount of evidence and the evidence isn’t sufficient to draw an absolute conclusion. While we are aware that there are biological, behavioral and environmental variables which play a significant role in women who live longer than males, it isn’t clear the extent to which each factor plays a role.
In spite of the amount of weight, we are aware that a large portion of the reason women live longer than men and not in the past, is to relate to the fact that a number of key non-biological factors have changed. These factors are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Some are more complex. For example, there is evidence that in rich countries the female advantage increased in part because infectious diseases used to affect women disproportionately a century ago, so advances in medicine that reduced the long-term health burden from infectious diseases, especially for survivors, ended up raising women’s longevity disproportionately.
Everywhere in the world women tend to live longer than men
The first chart below shows life expectancy at birth for men and women. It is clear that all countries are above the diagonal line of parity. This means that a newborn girl from any country can anticipate to live longer than her older brother.
The chart above shows that the advantage of women exists across all countries, the global differences are significant. In Russia, women live 10 years more than men. In Bhutan there is a difference of less that half a year.
The advantage of women in life expectancy was smaller in developed countries that it is today.
Let’s see how the female longevity advantage has changed in the course of time. The following chart shows the gender-based and female-specific life expectancy at birth in the US during the period 1790 to 2014. Two points stand out.
First, there is an upward trend. Both men and women in the US have a much longer life span longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.
The gap is getting wider: Although the female advantage in life expectancy was once extremely small It has significantly increased with time.
