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 is the reason women live much longer than men today, and why have these advantages gotten bigger in the past? There is only limited evidence and the evidence isn't sufficient to draw an informed conclusion. We are aware that behavioral, biological and اوضاع الجماع (try this) environmental factors all contribute to the fact that women have longer life spans than men, however, we aren't sure how significant the impact of each of these factors is.

We have learned that women are living longer than men, regardless of their weight. However this is not due to the fact that certain biological factors have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. There are others that are more intricate. 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 we can see, all countries are above the diagonal parity line , this means that in all countries that a baby girl can be expected to live longer than a newborn boy.1

This graph shows that although there is a women's advantage across all countries, differences between countries could be significant. In Russia women live 10 years longer than males. In Bhutan there is a difference of just half a year.

The female advantage in terms of life expectancy was lower in the richer countries than it is today.
Let's now look at how the gender advantage in longevity has changed with time. The next chart plots male and female life expectancies when they were born in the US over the period 1790-2014. Two specific points stand out.

The first is that there is an upward trend. Men and women in the United States live longer than they were a century ago. This is in line with historical increases in life expectancy everywhere in the world.

And second, there is an ever-widening gap: female advantage in terms of life expectancy used to be very small however, it has increased significantly during the last century.

It is possible to verify that the points you've listed are applicable to other countries with data by clicking on the "Change country" option on the chart. This includes the UK, France, and Sweden.
