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's the reason women are more likely to live longer than men? What is the reason is this difference growing as time passes? The evidence isn't conclusive and we're only able to provide some solutions. We know that biological, behavioral and environmental factors all play a role in the fact that women have longer life spans than men, however, we do not know how strong the relative contribution to each of these variables is.

In spite of the amount of weight, we are aware that at least a portion of the reason women live so much longer than men do today but not previously, has to do with the fact that a number of significant non-biological elements 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.
