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 Fakeplanes.tech/wiki/index.php/Why_Do_Women_Live_Longer_Than_Men how does this benefit increase as time passes? There isn’t much evidence and we’re only able to provide partial answers. Although we know that there are biological, behavioral as well as environmental factors that all play a role in women living longer than men, we do not know the extent to which each factor plays a role.
We are aware that women live longer than men, regardless of weight. But this isn’t due to the fact that certain non-biological factors have changed. What are these factors that have changed? Some are well known and relatively straightforward, like the fact that men smoke more often. There are other issues 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. We can see that every country is above the diagonal parity line , which means that in every country baby girls can expect to live for longer than a new boy.1
The chart above shows that, while the advantage for women exists across all countries, the difference between countries is huge. In Russia women are 10 years older than men; in Bhutan the gap is just half an hour.

In rich countries the women’s advantage in longevity was previously smaller.
Let’s see how the female longevity advantage has changed over time. The next chart compares the male and female lifespans at birth in the US between 1790 and 2014. Two specific points stand out.
There is an upward trend. Women and men in America have longer lives 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 ever-widening gap: female advantage in life expectancy used to be very modest however, it has increased significantly in the past century.
If you select the option “Change country’ on the chart, you can determine if these two points also apply to other countries that have available information: Sweden, France and the UK.
