Why do women live longer than men?

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 live longer than men? What is the reason does this benefit increase in the past? The evidence isn’t conclusive and we have only partial answers. We know that behavioral, biological and environmental factors all contribute to the fact that women are healthier than men; however, we do not know what the contribution of each factor is.

In spite of the amount of weight, we are aware that at least part of the reason why women live longer than men today but not previously, is to be due to the fact that certain significant non-biological elements have changed. The factors changing are numerous. Some are well known and relatively straightforward, Www.crazyquietgirl.com/__media__/js/netsoltrademark.php?d=glorynote.com%2F%25D8%25B2%25D9%258A%25D9%2588%25D8%25AA-%25D8%25AA%25D8%25B7%25D9%2588%25D9%258A%25D9%2584-%25D8%25A7%25D9%2584%25D8%25B4%25D8%25B9%25D8%25B1%2F 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.

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 all countries are over the line of parity diagonally. This implies that a baby girl from every country could expect to live longer than her older brother.

This chart illustrates that, although women have an advantage across all countries, differences between countries are often significant. In Russia, women live 10 years longer than males. In Bhutan the gap is less that half a year.

The advantage women had in life expectancy was smaller in developed countries that it is today.

Let’s examine how the female longevity advantage has changed over time. The next chart plots male and female life expectancies at birth in the US during the time period between 1790 and 2014. Two specific points stand out.

First, there is an upward trend. Women and men living in America are living longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is getting wider: Although the advantage of women in terms of life expectancy was very small but it has risen significantly in the past.

You can confirm that these principles 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.
