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 much longer than men today, and why is this difference growing in the past? We have only a small amount of evidence and ماذا يحدث بين الزوجين في الحمام بالصور - linked web site, the evidence is not sufficient to support an absolute conclusion. We recognize that biological, behavioral and environmental factors play a role in the fact that women are healthier than men; However, we're not sure how significant the impact of each one of these factors is.

We know that women are living longer than males, regardless of weight. But this is not because of certain non-biological factors have changed. What are the factors that are changing? Some are well known and relatively straightforward, like the fact that men smoke more often. Certain 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. We can see that all countries are above the diagonal line of parity. This implies that a baby girl in every country can be expected to live for longer than her brothers.

Interestingly, this chart shows that while the female advantage is present everywhere, cross-country differences are large. In Russia women are 10 years older than men; in Bhutan the difference is less than half a year.

In wealthy countries, the female advantage in longevity was smaller
Let's look at how the advantage of women in life expectancy has changed over time. The next chart compares male and female life expectancy when they were born in the US between 1790 and 2014. Two points stand out.

The first is that there is an upward trend. and women in the US are living much, much longer today than 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 female advantage in terms of life expectancy was tiny but it has risen significantly over time.

You can verify that these principles are also applicable to other countries that have data by selecting the "Change country" option in the chart. This includes the UK, France, and Sweden.
