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 much longer than men today and why has this advantage increased over time? There isn't much evidence and we only have limited answers. We are aware that behavioral, biological and environmental factors all play a role in the fact that women live longer than men; however, we aren't sure how significant the impact of each factor is.

We have learned that women live longer than men, regardless of their weight. But this isn't due to the fact that certain biological factors have changed. These are the factors that are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Others 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.
