Why women are more likely to live longer than men?

Jetta Tedesco (2022-04-21)


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 the advantage has grown over time? There is only limited evidence and the evidence is not sufficient to draw a definitive conclusion. We recognize that biological, behavioral and environmental factors all play a role in the fact that women have longer life spans than men, but we don't know exactly how significant the impact of each factor is.

We know that women live longer than males, regardless of weight. However this isn't due to the fact that certain non-biological aspects have changed. What are these factors that have changed? Some are well known and relatively straightforward, like the fact that men smoke more often. Some are more complex. For زيوت تطويل الشعر; glorynote.com, 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 , which means that in every country a newborn girl can expect to live for longer than a newborn boy.1

This graph shows that although women have an advantage everywhere, cross-country differences can be significant. In Russia women have a longer life span than males; while in Bhutan the difference is less than half a year.

In countries with high incomes, the female advantage in longevity was previously smaller.
Let's take a look at how the female longevity advantage has changed in the course of time. The next chart plots the male and female lifespans when they were born in the US between 1790 and 2014. Two things stand out.

First, there is an upward trend. and 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.

There is a widening gap: The female advantage in life expectancy used be quite small, but it grew substantially over the last century.

You can verify that these points are also applicable to other countries that have data by clicking the "Change country" option in the chart. This includes the UK, France, and Sweden.فيكتوزا-للتنحيف.jpg
