Why Do 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 much longer than men today and how have these advantages gotten bigger in the past? There is only limited evidence and the evidence is not strong enough to make an unambiguous conclusion. While we are aware that there are behavioral, biological and زيوت تطويل الشعر environmental variables that play an integral role in the longevity of women over men, we do not know the extent to which each factor plays a role.

We have learned that women are living longer than men, regardless of weight. But, this is not due to the fact that certain biological factors have changed. What are these new factors? 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 زيوت تطويل الشعر (similar web page) women. As you can see, all countries are above the diagonal parity line - it means that in all nations a newborn girl can expect to live for longer than a newborn boy.1

Interestingly, this chart shows that the advantage of women exists in all countries, cross-country differences are large. In Russia women have a longer life span than men. In Bhutan the gap is less than half each year.

In wealthy countries, the women's advantage in longevity was not as great.
We will now examine how the advantage of women in terms of longevity has changed over time. The next chart compares the life expectancy of males and females when they were born in the US during the time period between 1790 and 2014. Two distinct features stand out.

There is an upward trend. Women and men in the United States live longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is getting wider: Although the advantage of women in life expectancy was tiny however, it has grown significantly over time.
