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 longer than men and how have these advantages gotten bigger in the past? We have only a small amount of evidence and the evidence is not sufficient to support an absolute conclusion. We know there are biological, behavioral and environmental factors that all play a role in women living longer than males, it isn't clear how much each one contributes.

In spite of how much amount of weight, we are aware that at least part of the reason women live so much longer than men do today, but not previously, has to have to do with the fact that certain key non-biological factors have changed. What are these new factors? Some are well known and relatively straightforward, like the fact that men smoke more often. Other 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, افضل شامبو وبلسم 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 line of parity diagonally. This means that a newborn girl in all countries can anticipate to live longer than her brothers.

The chart above shows that, while the advantage for women exists in all countries, difference between countries is huge. In Russia, women live 10 years more than men. In Bhutan the difference is only half a year.

The female advantage in terms of life expectancy was lower in developed countries than it is now.
Let's now look at how the female advantage in terms of longevity has changed over time. The chart below illustrates the gender-based and female-specific life expectancy at the birth in the US from 1790 to 2014. Two specific points stand out.

First, there is an upward trend. Both genders in the United States live longer than they used to 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is widening: While the female advantage in terms of life expectancy was extremely small but it has risen significantly over time.

You can check if these points are also applicable to other countries with information by clicking on the "Change country" option in the chart. This includes the UK, France, and Sweden.
