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 why women live longer than men? And why has this advantage gotten larger in the past? The evidence is sketchy and we're left with only limited solutions. While we are aware that there are behavioral, biological and environmental factors that all play a role in women who live longer than males, we aren't sure how much each factor اوضاع الجماع (glorynote.com) contributes.

Independently of the exact weight, we know that at a minimum, the reason why women live so much longer than men today, but not in the past, has to relate to the fact that several key non-biological factors have changed. What are these factors that have changed? Some are well known and relatively straightforward, like the fact that men smoke more often. Some 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.

The first chart below shows life expectancy at birth for men and women. We can see that every country is over the diagonal line of parity. This implies that a baby girl from any country can be expected to live for longer than her brother.

It is interesting to note that while the female advantage is present everywhere, difference between countries is huge. In Russia, women live 10 years longer than men. In Bhutan the gap is less than half a calendar year.
