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 is the reason women have a longer life span than men? What is the reason the advantage has grown over time? There isn’t much evidence and we have only incomplete solutions. We recognize that biological, behavioral and environmental factors contribute to the fact that women have longer life spans than men, but we don’t know exactly what the contribution of each factor is.

In spite of the number of pounds, we know that at least a portion of the reason why women live longer than men do today however not as in the past, is to do with the fact that some fundamental non-biological factors have changed. These factors are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. There are other issues that are more intricate. 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 Www.consulenzaleonardo.com/modules.php?name=Your_Account&op=userinfo&username=MatthiasCc 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 above the line of parity diagonally. This means that a newborn girl in every country can expect to live longer than her brother.

The chart above shows that while the female advantage exists everywhere, the cross-country differences are large. In Russia women live for 10 years longer than males. In Bhutan the difference is less than half a calendar year.



In wealthy countries, the advantage of women in longevity was not as great.

Let’s examine how the female longevity advantage has changed over time. The following chart shows male and female life expectancies when they were born in the US during the time period between 1790 and 2014. Two points stand out.

First, there is an upward trend. Women and men in America have longer lives than they used to a century ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is widening: While the advantage of women in life expectancy was once tiny, it has increased substantially in the past.
