Why women are more likely to live longer than men?

Ferne Sisk (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 main reason women are more likely to live longer than men? What is the reason is this difference growing as time passes? The evidence is sketchy and كيفية ممارسة العلاقة الزوجية فى الاسلام we're only able to provide partial solutions. Although we know that there are behavioral, biological, and environmental factors that play an integral role in the longevity of women over males, we aren't sure what percentage each factor plays in.

Independently of the exact weight, we know that at least a portion of the reason women live longer than men but not in the past, is to relate to the fact that certain key 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. 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. As we can see, all countries are above the diagonal parity line ; this means in all countries a newborn girl can expect to live longer than a newborn boy.1

This chart illustrates that, even though women enjoy an advantage throughout the world, the differences between countries could be significant. In Russia women live 10 years longer than males; while in Bhutan the gap is just half each year.

The female advantage in life expectancy was less in developed countries than it is now.
Let's see how the female longevity advantage has changed over time. The following chart shows male and female life expectancy at birth in the US between 1790 and 2014. Two things stand out.

First, there's an upward trend. and women in the US have a much longer life span longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

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