Why do women have longer lives than men?

Everywhere in the world women live longer than men — .http://workingcaptialloan.com/__media__/js/netsoltrademark.php?d=glorynote.com. 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 the advantage has grown in the past? We have only a small amount of evidence and the evidence is not sufficient to draw a definitive conclusion. We know there are behavioral, biological as well as environmental factors that play an integral role in women who live longer than males, it isn’t clear the extent to which each factor plays a role.

It is known that women are living longer than men, regardless of their weight. However, 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. 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. As you can see, all countries are above the diagonal parity line — this means that in all countries baby girls can expect to live for longer than a new boy.1

This chart is interesting in that it shows that while the female advantage is present everywhere, global differences are significant. In Russia, women live for 10 years longer than males. In Bhutan there is a difference of only half a year.

In countries with high incomes, the female advantage in longevity was not as great.
Let’s look at how the advantage of women in longevity has changed with time. The following chart shows the men and women’s life expectancies when they were born in the US between 1790 to 2014. Two areas stand out.

There is an upward trend. Men as well as women in the US live a lot, much longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

There is an increasing gap: The female advantage in life expectancy used to be very small however it increased dramatically over the course of the last century.
