Why do women live 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? What is the reason does this benefit increase as time passes? We have only a small amount of evidence and the evidence isn’t sufficient to draw an unambiguous conclusion. We know there are biological, psychological, and environmental factors which all play a part in women who live longer than males, we aren’t sure how much each factor contributes.
We know that women are living longer than men, regardless of weight. But, this is not due to the fact that certain biological factors have changed. What are these factors that have changed? 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. It is clear that every country is above the diagonal line of parity. This means that a newborn girl in all countries can be expected to live for longer than her younger brother.
Interestingly, this chart shows that, while the advantage for women exists across all countries, the difference between countries is huge. In Russia women live 10 years more than men. In Bhutan the gap is less than half a calendar year.

The advantage women had in terms of life expectancy was lower in rich countries than it is today.
Let’s look at the way that female advantages in life expectancy has changed over time. The following chart shows male and زيوت تطويل الشعر, just click the up coming page, female life expectancy at birth in the US between 1790 and 2014. Two points stand out.
The first is that there is an upward trend: Men as well as women in the US live a lot, much longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.
The gap is widening: While the advantage of women in life expectancy was once tiny It has significantly increased in the past.
