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 much longer than men today and why does this benefit increase over time? There is only limited evidence and the evidence is not sufficient to support a definitive conclusion. We know that behavioral, biological and environmental factors play a role in the fact that women have longer life spans than men, However, we're not sure how significant the impact to each of these variables is.

In spite of the precise amount of weight, we are aware that at a minimum, ماذا يحدث بين الزوجين في الحمام بالصور the reason women live so much longer than men today, but not previously, has to relate to the fact that several fundamental 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. 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 ماذا يحدث بين الزوجين في الحمام بالصور 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 all countries are over the diagonal line of parity. This implies that a baby girl in every country can expect to live longer than her older brother.

The chart above shows that while the female advantage exists across all countries, the country-specific differences are huge. In Russia, women live 10 years longer than men. In Bhutan the difference is only half a year.

In the richer countries, the advantage of women in longevity was not as great.
Let's examine how the advantage of women in terms of longevity has changed over time. The chart below shows male and female life expectancy when they were born in the US in the years 1790 to 2014. Two aspects stand out.

There is an upward trend. Men and women living in America are living longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

And second, there is an increase in the gap between men and women: female advantage in life expectancy used to be extremely small but it increased substantially over the course of the last century.

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