Why women are more likely to live longer than men?

Mellissa Rodman (2022-04-20)

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? And how is this difference growing as time passes? We only have a few clues and the evidence isn't sufficient to support an unambiguous conclusion. Although we know that there are behavioral, biological as well as environmental factors that all play a role in the longevity of women over men, we do not know how much each factor contributes.

In spite of how much amount of weight, كيفية ممارسة العلاقة الزوجية فى الاسلام we are aware that at least part of the reason women live so much longer than men in the present however not as previously, has to relate to the fact that some fundamental non-biological factors have changed. What are the factors that are changing? 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.

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 ; this means in all countries that a baby girl can be expected to live longer than a newborn boy.1

The chart above shows that although the female advantage exists across all countries, the global differences are significant. In Russia women have a longer life span than men, while in Bhutan the difference is less than half an hour.

The advantage for women in terms of life expectancy was lower in the richer countries than it is now.
Let's take a look at how the female longevity advantage has changed over time. The chart below illustrates the male and female life expectancies when they were born in the US between 1790 to 2014. Two areas stand out.

First, there is an upward trend. Both genders in America have longer lives than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is widening: While the advantage of women in terms of life expectancy was quite small however, it has grown significantly over time.
