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 why women have a longer life span than men? And why the advantage has grown over time? We only have partial evidence and the evidence isn't sufficient to support a definitive conclusion. We know there are biological, psychological and environmental variables which play a significant role in women who live longer than males, we aren't sure what percentage each factor plays in.

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.
