Why women are more likely to 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 have a longer life span than men? What is the reason does this benefit increase as time passes? We only have partial evidence and the evidence isn’t sufficient to reach a definitive conclusion. We are aware that behavioral, biological and environmental factors all contribute to the fact that women have longer lives than men, however, we do not know how strong the relative contribution of each one of these factors is.

We know that women are living longer than men, regardless of weight. But this isn’t due to the fact that certain biological factors have changed. What are the factors that are changing? Some are well known and relatively straightforward, like the fact that men smoke more often. Other are more complicated. 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.
