Why are women living longer than men?

Shawnee Kiley (2022-04-19)

شامبو-امالفي-للبروتينEverywhere 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 have a longer life span than men? Why is this difference growing in the past? We only have a few clues and the evidence isn't strong enough to make an unambiguous conclusion. Although we know that there are biological, psychological, and زيوت تطويل الشعر environmental factors which all play a part in the longevity of women over men, we don't know what percentage each factor plays in.

It is known that women live longer than males, regardless of weight. But, this is not due to the fact that certain non-biological factors have changed. What are these new factors? 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. It is clear that every country is over the diagonal line of parity. This implies that a baby girl in every country can be expected to live for longer than her older brother.

Interestingly, this chart shows that, زيوت تطويل الشعر while the advantage for women exists in all countries, difference between countries is huge. In Russia, women live 10 years longer than males. In Bhutan the gap is less that half a year.

The advantage for women in terms of life expectancy was lower in countries with higher incomes than it is today.
Let's look at how the gender advantage in longevity has changed with time. The next chart shows male and female life expectancies when they were born in the US between 1790 and 2014. Two points stand out.

The first is that there is an upward trend. Both genders in America live longer than they used to 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The second is that there is an increasing gap: The female advantage in life expectancy used to be very small, but it grew substantially over the last century.

You can confirm that these points are also applicable to other countries that have information by clicking on the "Change country" option on the chart. This includes the UK, France, and Sweden.
