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 live longer than men, and Www.atari-wiki.com/index.php/User:SantoBci9857 why has this advantage increased in the past? We have only a small amount of evidence and the evidence isn’t sufficient to draw a definitive conclusion. We know there are biological, behavioral and environmental factors which play a significant role in women who live longer than males, we aren’t sure how much each one contributes.
In spite of the amount, we can say that at least a portion of the reason why women live longer than men do today but not previously, has to have to do with the fact that a number of fundamental non-biological factors have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Others 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, 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 line of parity diagonally. This implies that a baby girl from any country can anticipate to live longer than her younger brother.
It is interesting to note that, while the advantage for women is present everywhere, difference between countries is huge. In Russia women have an average of 10 years more than men. In Bhutan the difference is less than half an hour.
The female advantage in terms of life expectancy was lower in rich countries than it is now.
Let’s take a look at how the female longevity advantage has changed over time. The next chart compares male and female life expectancy at birth in the US during the time period between 1790 and 2014. Two distinct points stand out.
First, there is an upward trend: Men and women in the US have a much longer life span longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.
Second, there’s an increase in the gap between men and women: female advantage in life expectancy used to be very small however, it has increased significantly over the course of the last century.
You can verify that these principles are also applicable to other countries that have data by selecting the “Change country” option in the chart. This includes the UK, France, and Sweden.
