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 main reason women have a longer life span than men? And how has this advantage gotten larger over time? The evidence isn't conclusive and we're left with only some solutions. Although we know that there are biological, behavioral and environmental factors which play a significant role in women living longer than males, it isn't clear the extent to which each factor plays a role.

In spite of how much amount of weight, we are aware that a large portion of the reason women live longer than men in the present and not previously, is to have to do with the fact that a number of important non-biological aspects have changed. What are these factors that have changed? 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 Wikiflight.net/index.php?title=Why_Are_Women_Living_Longer_Than_Men 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 you can see, every country is above the diagonal line of parity - which means that in every country the newborn girl is likely to live for longer than a newborn boy.1

This graph shows that although women have an advantage throughout the world, the differences between countries could be significant. In Russia women live 10 years longer than men. In Bhutan, the difference is only half a year.

The female advantage in life expectancy was much lower in developed countries than it is today.
Let's examine how the gender advantage in longevity has changed over time. The chart below illustrates the male and female life expectancy at the birth in the US in the years 1790-2014. Two distinct points stand out.

The first is that there is an upward trend. Both genders in America have longer lives than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

And second, there is a widening gap: The female advantage in life expectancy used be extremely small but it increased substantially over the last century.
