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 has this advantage increased over time? There isn't much evidence and we only have limited answers. We are aware that behavioral, biological and environmental factors all play a role in the fact that women live longer than men; however, we aren't sure how significant the impact of each factor is.

We have learned that women live longer than men, regardless of their weight. But this isn't due to the fact that certain biological factors 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 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, 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 ; this means in all countries the newborn girl is likely to live for افضل شامبو وبلسم; go to glorynote.com, longer than a new boy.1

Interestingly, this chart shows that the advantage of women is present everywhere, difference between countries is huge. In Russia women live 10 years more than men. In Bhutan there is a difference of just half a year.

In countries with high incomes, the female advantage in longevity used to be smaller
Let's examine how the female longevity advantage has changed over time. The next chart plots male and female life expectancies at birth in the US from 1790 to 2014. Two things stand out.

First, there's an upward trend. Men as well as women in the US have a much longer life span longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

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

Using the option 'Change country in the chart, you will be able to verify that these two points apply to the other countries having available data: Sweden, France and the UK.
