Why Do Women Have Longer Lives 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 are more likely to live longer than men? What is the reason is this difference growing as time passes? There is only limited evidence and the evidence is not strong enough to make an absolute conclusion. We know there are behavioral, biological and environmental variables that play an integral role in women's longevity more than males, it isn't clear the extent to which each factor plays a role.

In spite of how much weight, we know that at a minimum, the reason women live so much longer than men, but not previously, has to do with the fact that a number of key non-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. Others are more complicated. 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, all countries are above the diagonal parity line , this means in all countries the newborn girl is likely to live for longer than a newborn boy.1

This graph shows that even though women enjoy an advantage throughout the world, the differences between countries are often significant. In Russia, women live for ابر التخسيس 10 years longer than men. In Bhutan the gap is just half a year.

In the richer countries, the female advantage in longevity was not as great.
Let's see how the female longevity advantage has changed in the course of time. The chart below shows male and female life expectancy at the birth in the US during the period 1790 to 2014. Two aspects stand out.

There is an upward trend. Men as well as 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 second is that there is an increasing gap: The female advantage in life expectancy used be extremely small however, it has increased significantly during the last century.
