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 have a longer life span than men? And how has this advantage gotten larger as time passes? We have only a small amount of evidence and the evidence is not sufficient to reach an unambiguous conclusion. While we are aware that there are biological, behavioral, and environmental factors that all play a role in women living longer than males, كيفية إقامة علاقة بالصور we aren't sure how much each factor contributes.

In spite of the precise weight, we know that at a minimum, the reason women live so much longer than men today but not in the past, has to be due to the fact that a number of key non-biological factors have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Others are more complicated. For example, كيفية إقامة علاقة بالصور 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 every country is above the diagonal parity line , it means that in all nations baby girls can expect to live for longer than a newborn boy.1

The chart below shows that although women have an advantage throughout the world, the differences between countries can be significant. In Russia women have a longer life span than men, while in Bhutan the gap is less than half an hour.

The advantage women had in life expectancy was smaller in rich countries that it is today.
Let's see how the female longevity advantage has changed in the course of time. The chart below shows men and women's life expectancies at the birth in the US between 1790-2014. Two things stand out.

First, there's an upward trend. Men and women in the US have a much longer life span longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The second is that there is an increasing gap: The female advantage in life expectancy used to be quite small, but it grew substantially over the course of the last century.

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