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 so more than men do today and how has this advantage increased in the past? The evidence is limited and we're only able to provide some solutions. We are aware that behavioral, biological and environmental factors all play a role in the fact that women have longer lives than men, however, we do not know how much the influence to each of these variables is.

It is known that women are living longer than men, regardless of their weight. However this isn't due to the fact that certain non-biological aspects have changed. The factors changing are numerous. Some are well known and relatively straightforward, اضيق وضعية للجماع like the fact that men smoke more often. Others 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 اضيق وضعية للجماع men and women. As you can see, every country is above the diagonal parity line ; this means that in all countries baby girls can expect to live longer than a new boy.1

Interestingly, this chart shows that although the female advantage exists everywhere, the difference between countries is huge. In Russia women live 10 years longer than males. In Bhutan there is a difference of less than half a calendar year.

The advantage women had in life expectancy was smaller in developed countries that it is today.
Let's look at how 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 in the years 1790 to 2014. Two areas stand out.

First, there's an upward trend. and 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.

Second, there's an increasing gap: The female advantage in life expectancy used to be extremely small however, it has increased significantly over the last century.
