Difference between revisions of "Why Do Women Have Longer Lives Than Men"

Revision as of 18:35, 12 January 2022

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 reason women are more likely to live longer than men? What is the reason is this difference growing over time? The evidence is limited and we're only able to provide incomplete solutions. While we are aware that there are biological, behavioral and environmental variables which play a significant role in women's longevity more than males, we aren't sure what percentage each factor plays in.

Independently of the exact weight, ماذا يحدث بين الزوجين في الحمام بالصور we know that a large portion of the reason why women live longer than men do today and not previously, ماذا يحدث بين الزوجين في الحمام بالصور (glorynote.com) is to do with the fact that certain important non-biological aspects have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Others 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. It is clear that every country is above the diagonal line of parity. This means that a newborn girl in all countries can be expected to live for longer than her brothers.

The chart below shows that although there is a women's advantage in all countries, the differences across countries are often significant. In Russia women live 10 years longer than men; in Bhutan the gap is less than half a year.

In the richer countries, the women's advantage in longevity used to be smaller
Let's see how the female longevity advantage has changed over time. The chart below illustrates the men and women's life expectancies at birth in the US from 1790-2014. Two specific points stand out.

The first is that there is an upward trend: Men and women in the US are living much, much longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is getting wider: Although the advantage of women in life expectancy was once tiny, it has increased substantially over time.

You can check if these are applicable to other countries that have data by clicking the "Change country" option in the chart. This includes the UK, France, and Sweden.
