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 why women have a longer life span than men? What is the reason has this advantage gotten larger in the past? We only have a few clues and the evidence is not sufficient to reach an absolute conclusion. We know that biological, behavioral and environmental factors all contribute to the fact that women are healthier than men; however, we do not know how much the influence of each factor is.

We are aware that women live longer than men, regardless of their weight. But, this is not due to the fact that certain non-biological factors have changed. What are these changing factors? 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.
