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 much longer than men today, and why have these advantages gotten bigger over time? There isn't much evidence and we're only able to provide partial solutions. Although we know that there are biological, behavioral and environmental factors which all play a part in the longevity of women over men, we don't know how much each one contributes.

In spite of how much weight, we know that at least part of the reason women live so much longer than men but not in the past, is to be due to the fact that several significant non-biological elements have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Others are more complicated. For زيوت تطويل الشعر 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 زيوت تطويل الشعر men and women. It is clear that every country is over the line of parity diagonally. This implies that a baby girl from any country can be expected to live for longer than her brothers.

Interestingly, this chart shows that although the female advantage exists everywhere, the global differences are significant. In Russia, women live 10 years longer than men. In Bhutan, the difference is less than half a calendar year.

In rich countries the women's advantage in longevity was previously smaller.
Let's examine how the 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 is an upward trend. Men and women in the US live much, 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 growing: Although the advantage of women in life expectancy was once tiny but it has risen significantly over time.

You can check if the points you've listed are applicable to other countries with data by selecting the "Change country" option on the chart. This includes the UK, France, and Sweden.
