Why women live longer than men?
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. What is the reason women live longer than men and why is this difference growing in the past? We only have partial evidence and the evidence isn’t sufficient to reach an unambiguous conclusion. While we are aware that there are biological, behavioral, and environmental factors which all play a part in the longevity of women over men, we do not know the extent to which each factor plays a role.
We are aware that women are living longer than men, regardless of weight. But this isn’t because of certain biological factors have changed. What are the factors that are changing? Some are well known and relatively straightforward, like the fact that men smoke more often. Other are more complicated. 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 every country is above the line of parity diagonally. This means that a newborn girl from every country could expect to live longer than her brother.
This chart illustrates that, while there is a female advantage throughout the world, the differences between countries are often significant. In Russia women have a longer life span than men, while in Bhutan the difference is just half one year.

In wealthy countries, ماذا يحدث بين الزوجين في الحمام بالصور the advantage of women in longevity was not as great.
Let’s see how the female longevity advantage has changed in the course of time. The chart below shows male and female life expectancy when they were born in the US in the years 1790 to 2014. Two areas stand out.
First, there is an upward trend. Both men as well as women in the US are living much, much longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.
The gap is widening: While the female advantage in terms of life expectancy was extremely small however, it has grown significantly over time.
