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. Why do women live longer than men and why has this advantage increased over time? We have only a small amount of evidence and the evidence is not sufficient to support an absolute conclusion. Although we know that there are behavioral, biological as well as environmental factors which play a significant role in women who live longer than men, زيوت تطويل الشعر; Glorynote.com post to a company blog, we do not know the extent to which each factor plays a role.

In spite of the precise amount of weight, we are aware that at a minimum, the reason women live so much longer than men, but not previously, is to have to do with the fact that several important non-biological aspects have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. There are other issues that are more intricate. 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. As we can see, every country is above the diagonal parity line , this means in all countries the newborn girl is likely to live for longer than a new boy.1

Interestingly, this chart shows that, while the advantage for women exists in all countries, difference between countries is huge. In Russia women have a longer life span than males; while in Bhutan the difference is just half each year.

In wealthy countries, the female advantage in longevity was smaller
Let's take a look at how the female longevity advantage has changed over time. The following chart shows the men and women's life expectancies when they were born in the US from 1790 until 2014. Two points stand out.

There is an upward trend. Both men and women in the US live a lot, 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 increasing: While the advantage of women in life expectancy used to be very small but it has risen significantly over time.
