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 makes women live longer than men and why is this difference growing in the past? The evidence is limited and we’re only able to provide some solutions. While we are aware that there are biological, psychological as well as environmental factors which all play a part in the longevity of women over males, it isn’t clear the extent to which each factor plays a role.
In spite of the amount of weight, we are aware that at least a portion of the reason women live longer than men do today but not previously, has to do with the fact that certain important non-biological aspects 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, ابر التخسيس 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, every country is above the diagonal line of parity – this means that in all countries baby girls can expect to live longer than a new boy.1
It is interesting to note that while the female advantage exists everywhere, ابر التخسيس (https://glorynote.com/) the difference between countries is huge. In Russia women are 10 years older than males; while in Bhutan the gap is just half one year.

The advantage of women in life expectancy was less in countries with higher incomes than it is today.
Let’s look at how the female advantage in longevity has changed with time. The next chart shows male and female life expectancies when they were born in the US from 1790 to 2014. Two distinct features stand out.
The first is that there is an upward trend. Women and men in America have longer lives 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 female advantage in terms of life expectancy was quite small It has significantly increased over time.
It is possible to verify that these are applicable to other countries that have information by clicking on the “Change country” option on the chart. This includes the UK, France, and Sweden.
