Why 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 in the present, and why have these advantages gotten bigger over time? There isn’t much evidence and we’re left with only some solutions. We know that biological, behavioral and environmental factors play a role in the fact that women live longer than men; however, we do not know how strong the relative contribution of each factor is.

We are aware that women live longer than men, regardless of their weight. However, this is not due to the fact that certain 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. There are others 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.
