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 longer than men in the present and why is this difference growing in the past? The evidence is sketchy and we're only able to provide incomplete answers. Although we know that there are biological, psychological and environmental variables that all play a role in women who live longer than men, we don't know what percentage each factor plays in.

In spite of the amount of weight, we are aware that at least part of the reason why women live longer than men in the present and not previously, ماذا يحدث بين الزوجين في الحمام بالصور has to relate to the fact that certain important non-biological aspects have changed. What 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 ماذا يحدث بين الزوجين في الحمام بالصور women. We can see that all countries are over the diagonal line of parity. This means that a newborn girl from every country could be expected to live for longer than her brother.

It is interesting to note that while the female advantage exists everywhere, the cross-country differences are large. In Russia women live 10 years longer than men, while in Bhutan the difference is just half an hour.

In countries with high incomes, the women's advantage in longevity used to be smaller
Let's examine the way that female advantages in terms of longevity has changed over time. The following chart shows the gender-based and female-specific life expectancy when they were born in the US between 1790 to 2014. Two points stand out.

First, there is an upward trend. Both men and 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 once extremely small, it has increased substantially over time.

You can confirm 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.
