Why are women living 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 have a longer life span than men? And why is this difference growing in the past? There isn’t much evidence and we’re left with only limited solutions. We recognize that biological, زيوت تطويل الشعر behavioral and environmental factors all contribute to the fact that women live longer than men; however, we aren’t sure how strong the relative contribution of each of these factors is.

We have learned 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. 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 women. We can see that all countries are over the diagonal line of parity. This means that a newborn girl in every country can expect to live longer than her younger brother.

It is interesting to note that although the female advantage exists across all countries, the difference between countries is huge. In Russia, women live 10 years longer than males. In Bhutan the gap is less than half a calendar year.

The advantage for women in life expectancy was much lower in rich countries that it is today.

Let’s examine how the female longevity advantage has changed over time. The next chart shows the life expectancy of males and females when they were born in the US during the time period between 1790 and 2014. Two specific points stand out.

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

The gap is increasing: زيوت تطويل الشعر (glorynote.com) While the advantage of women in life expectancy was once quite small but it has risen significantly with time.

You can verify that these principles are also applicable to other countries that have data by clicking on the “Change country” option in the chart. This includes the UK, France, and Sweden.
