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. Why do women live so much longer than men today and why does this benefit increase over time? There is only limited evidence and the evidence is not strong enough to make a definitive conclusion. We know that behavioral, biological and environmental factors all play a role in the fact that women have longer lives than men, however, we do not know how significant the impact to each of these variables is.

In spite of how much number of pounds, we know that a large portion of the reason women live so much longer than men in the present however not as in the past, is to relate to the fact that certain fundamental non-biological factors have changed. What are these factors that have changed? Some are well known and ماذا يحدث بين الزوجين في الحمام بالصور (https://glorynote.com/) relatively straightforward, like the fact that men smoke more often. There are other issues that are more intricate. 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.

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 means that a newborn girl in all countries can be expected to live for longer than her brother.

It is interesting to note that, while the advantage for women exists across all countries, the cross-country differences are large. In Russia women have an average of 10 years more than men. In Bhutan the difference is less than half a year.

In rich countries the female advantage in longevity was not as great.
Let's examine how the female longevity advantage has changed in the course of time. The chart below shows gender-based and female-specific life expectancy at the time of birth in the US between 1790 to 2014. Two aspects stand out.

The first is that there is an upward trend. Men and women in the US are living 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 getting wider: Although the advantage of women in life expectancy was once extremely small It has significantly increased in the past.
