Why women are more likely to live longer than men?

Jett Alvarado (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 why women are more likely to live longer than men? And why has this advantage gotten larger as time passes? The evidence is sketchy and we have only limited answers. We know that biological, behavioral and اوضاع الجماع environmental factors play a role in the fact that women are healthier than men; however, we aren't sure how significant the impact of each of these factors is.

We know that women are living longer than males, regardless of weight. But this is not due to the fact that certain non-biological aspects have changed. What are these new factors? Some are well known and relatively straightforward, like the fact that men smoke more often. Other are more complicated. 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 all countries are over the line of parity diagonally. This implies that a baby girl in every country can anticipate to live longer than her younger brother.

This chart shows that, although women have an advantage throughout the world, the differences between countries can be significant. In Russia, women live 10 years longer than men. In Bhutan the difference is only half a year.

In rich countries the female advantage in longevity was previously smaller.
Let's now look at how the advantage of women in longevity has changed over time. The following chart shows the men and women's life expectancies at the birth in the US from 1790 until 2014. Two distinct features stand out.

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

The gap is increasing: اوضاع الجماع While the female advantage in life expectancy was once very small, it has increased substantially in the past.

You can verify that these points are also applicable to other countries with data by selecting the "Change country" option on the chart. This includes the UK, France, and Sweden.
