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 longer than men and why does this benefit increase in the past? The evidence is sketchy and we only have incomplete solutions. Although we know that there are biological, behavioral, and environmental factors that all play a role in women who live longer than males, it isn't clear what percentage each factor plays in.

In spite of the amount of weight, we are aware that a large portion of the reason women live so much longer than men do today and not previously, is to have to do with the fact that a number of important non-biological aspects have changed. These variables are evolving. 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.
