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 so more than men do today, and why have these advantages gotten bigger over time? We only have a few clues and the evidence is not sufficient to support an absolute conclusion. We know that behavioral, biological and environmental factors contribute to the fact that women live longer than men; however, we aren't sure how strong the relative contribution to each of these variables is.

In spite of how much number of pounds, اوضاع الجماع (https://glorynote.com/) we know that at a minimum, the reason why women live longer than men and not in the past, is to do with the fact that several important non-biological aspects have changed. These are the factors that are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Others 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.

Everywhere in the world women tend to live longer than men
The first chart below shows life expectancy at birth for men and women. As you can see, every country is above the diagonal parity line , which means that in every country baby girls can expect to live longer than a newborn boy.1

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

In countries with high incomes, the women's advantage in longevity used to be smaller
Let's examine how the female longevity advantage has changed in the course of time. The chart below shows gender-based and female-specific life expectancy at birth in the US from 1790 until 2014. Two points stand out.

The first is that there is an upward trend. Both genders living in America are living longer than they used to a century ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is growing: Although the female advantage in life expectancy was quite small, it has increased substantially over time.
