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 have a longer life span than men? And how has this advantage gotten larger over time? We only have partial evidence and the evidence isn't sufficient to support an unambiguous conclusion. We are aware that behavioral, biological and environmental factors contribute to the fact that women have longer lives than men, however, we aren't sure what the contribution of each of these factors is.

In spite of the precise amount, we can say that a large portion of the reason why women live longer than men but not previously, ماذا يحدث بين الزوجين في الحمام بالصور is to relate to the fact that some important non-biological aspects have changed. These factors are changing. 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, ماذا يحدث بين الزوجين في الحمام بالصور (https://glorynote.com/%D9%85%D8%A7%D8%B0%D8%A7-%D9%8A%D8%AD%D8%AF%D8%AB-%D8%A8%D9%8A%D9%86-%D8%A7%D9%84%D8%B2%D9%88%D8%AC%D9%8A%D9%86-%D9%81%D9%8A-%D8%A7%D9%84%D8%AD%D9%85%D8%A7%D9%85/) 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, every country is above the diagonal line of parity - which means that in every country a newborn girl can expect to live longer than a new boy.1

The chart below shows that although women have an advantage throughout the world, the differences between countries can be substantial. In Russia women have a longer life span than men. In Bhutan the gap is just half one year.

The advantage for women in terms of life expectancy was lower in developed countries as compared to the present.
Let's now look at how the advantage of women in longevity has changed over time. The following chart shows the male and female life expectancy at the time of birth in the US between 1790 to 2014. Two points stand out.

First, there is an upward trend. Both genders in America have longer lives than they used to a century ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is getting wider: Although the female advantage in terms of life expectancy was tiny however, it has grown significantly with time.

You can check if these principles are also applicable to other countries that have data by clicking on the "Change country" option on the chart. This includes the UK, France, and Sweden.
