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 makes women live more than men do today and how has this advantage increased over time? The evidence isn't conclusive and we only have some answers. We know that behavioral, biological and environmental factors all play a role in the fact that women live longer than men; but we don't know exactly how significant the impact to each of these variables is.

Independently of the exact amount of weight, we are aware that at least a portion of the reason why women live so much longer than men today, but not in the past, has to relate to the fact that some significant non-biological elements have changed. What are these changing factors? Some are well known and relatively straightforward, like the fact that men smoke more often. Some 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 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] women. It is clear that all countries are above the diagonal line of parity. This implies that a baby girl in all countries can be expected to live for longer than her brother.

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

In the richer countries, the longevity advantage for women was not as great.
Let's see how the female longevity advantage has changed in the course of time. The chart below shows male and female life expectancies when they were born in the US from 1790 to 2014. Two points stand out.

The first is that there is an upward trend. Men and women in the US live much, much longer than they did a century 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 very modest, but it grew substantially during the last century.

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