Why Are Women Living 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 are more likely to live longer than men? And ماذا يحدث بين الزوجين في الحمام بالصور how does this benefit increase as time passes? We have only a small amount of evidence and the evidence is not sufficient to support an informed conclusion. We are aware that behavioral, biological and environmental factors contribute to the fact that women have longer life spans than men, however, we aren't sure how much the influence of each of these factors is.

In spite of the weight, we know that a large portion of the reason why women live longer than men today, but not in the past, has to have to do with the fact that some significant non-biological elements have changed. What are the factors that are changing? 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.

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, all countries are above the diagonal line of parity - which means that in every country the newborn girl is likely to live longer than a newborn boy.1

Interestingly, this chart shows that although the female advantage exists everywhere, the country-specific differences are huge. In Russia women have a longer life span than men, while in Bhutan the gap is just half each year.

In wealthy countries, the longevity advantage for women was not as great.
We will now examine the way that female advantages in terms of longevity has changed over time. The chart below shows male and female life expectancy at the time of birth in the US in the years 1790 until 2014. Two aspects stand out.

First, there is an upward trend. Men as well as women in the US live a lot, much longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is widening: While the advantage of women in life expectancy was quite small but it has risen significantly over time.
