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 so longer than men, and why has this advantage increased over time? The evidence is limited and we have only some answers. We know there are biological, psychological as well as environmental factors that all play a role in women’s longevity more than males, we aren’t sure what percentage each factor plays in.
We are aware that women live longer than men, regardless of their weight. But this isn’t because of certain non-biological factors have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. There are other issues 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.
