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 live longer than men? What is the reason does this benefit increase in the past? The evidence isn't conclusive and we're only able to provide incomplete solutions. We know that biological, behavioral and environmental factors all contribute to the fact that women have longer lives than men, however, we aren't sure what the contribution of each one of these factors is.

In spite of the weight, we know that at least part of the reason why women live longer than men in the present however not as in the past, has to relate to the fact that certain fundamental non-biological factors have changed. These factors are changing. 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.
