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 more than men do today and why is this difference growing over time? The evidence is limited and we're only able to provide limited answers. While we are aware that there are biological, psychological and environmental variables which play a significant role in women living longer than males, we aren't sure what percentage each factor افضل كريم للشعر plays in.

In spite of how much amount of weight, we are aware that at least a portion of the reason women live so much longer than men do today, but not previously, is to have to do with the fact that a number of 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. 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, افضل كريم للشعر 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. We can see that every country is above the diagonal parity line , which means that in every country the newborn girl is likely to live longer than a newborn boy.1

The chart below shows that although women have an advantage everywhere, cross-country differences could be significant. In Russia, women live for 10 years longer than men. In Bhutan the gap is just half a year.

In rich countries the female advantage in longevity was not as great.
Let's look at how the female advantage in life expectancy has changed over time. The following chart shows the male and female life expectancies at birth in the US in the years 1790 to 2014. Two specific points stand out.

There is an upward trend: Men as well as women in the US have a much longer life span longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is getting wider: Although the advantage of women in life expectancy was extremely small It has significantly increased with time.
