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's the main reason women live longer than men? Why is this difference growing as time passes? The evidence is sketchy and we have only partial answers. While we are aware that there are biological, behavioral and environmental factors that all play a role in the longevity of women over men, we do not know how much each one contributes.

We have learned that women live longer than men, regardless of weight. However this isn't because of certain non-biological factors have changed. What are the factors that are changing? Some are well known and relatively straightforward, 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 زيوت تطويل الشعر 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. It is clear that every country is above the line of parity diagonally. This implies that a baby girl from every country could anticipate to live longer than her brother.

This chart is interesting in that it shows that although the female advantage is present everywhere, cross-country differences are large. In Russia, women live 10 years more than men. In Bhutan there is a difference of less that half a year.

In the richer countries, the advantage of women in longevity used to be smaller
Let's see how the female longevity advantage has changed in the course of time. The next chart compares male and female life expectancy when they were born in the US between 1790 and 2014. Two distinct features stand out.

First, there's an upward trend. 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.

And second, there is an ever-widening gap: female advantage in life expectancy used to be very small however, it has increased significantly over the course of the last century.

Using the option 'Change country by country' in the chart, زيوت تطويل الشعر - related web site - determine if these two points are applicable to the other countries having available information: Sweden, France and the UK.
