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 in the past? We only have a few clues and the evidence isn’t strong enough to make a definitive conclusion. We know that behavioral, biological and environmental factors contribute to the fact that women have longer lives than men, however, we do not know how significant the impact of each factor is.

We are aware that women are living longer than men, regardless of weight. However, this is not because of certain biological or 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. 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.
