Why Are Women Living 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 reason why women have a longer life span than men? Why the advantage has grown as time passes? There isn't much evidence and we have only some solutions. While we are aware that there are behavioral, biological and environmental factors which all play a part in the longevity of women over men, we do not know the extent to which each factor plays a role.

In spite of the number of pounds, we know that at least part of the reason why women live so much longer than men do today, but not previously, اضيق وضعية للجماع is to do with the fact that some significant non-biological elements have changed. The factors changing are numerous. 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.

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 expect to live longer than her younger brother.

Interestingly, this chart shows that the advantage of women exists across all countries, the country-specific differences are huge. In Russia women have an average of 10 years more than men. In Bhutan the difference is just half an hour.

The advantage of women in life expectancy was smaller in developed countries than it is today.
Let's look at how the advantage of women in life expectancy has changed over time. The chart below shows male and female life expectancy at the time of birth in the US between 1790-2014. Two areas stand out.

First, there's an upward trend. Both men as well as women in the US live 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: اضيق وضعية للجماع Although the female advantage in life expectancy was tiny It has significantly increased over time.
