Why women live longer than men?
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 live longer than men? Why does this benefit increase over time? There isn’t much evidence and we’re only able to provide incomplete solutions. While we are aware that there are biological, behavioral as well as environmental factors which all play a part in women who live longer than men, we don’t know the extent to which each factor plays a role.
In spite of the precise number of pounds, we know that a large portion of the reason women live longer than men in the present and not in the past, is to have to do with the fact that certain 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 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 parity line , Accounting.foursquare.org/wiki/index.php/User:NicholeZ92 it means that in all nations the newborn girl is likely to live longer than a new boy.1
This chart shows that, while there is a female advantage across all countries, differences between countries could be significant. In Russia women live 10 years more than men. In Bhutan the difference is only half a year.
In rich countries the longevity advantage for women was not as great.
Let’s look at how female longevity advantage has changed over time. The chart below illustrates the men and women’s life expectancies at the time of birth in the US between 1790-2014. Two points stand out.
The first is that there is an upward trend. Both men as well as 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.
The gap is widening: While the female advantage in life expectancy was extremely small It has significantly increased in the past.
