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 are more likely to live longer than men? Why the advantage has grown as time passes? The evidence isn't conclusive and we have only limited solutions. We recognize that biological, behavioral and environmental factors all contribute to the fact that women have longer life spans than men, However, we're not sure how strong the relative contribution of each factor is.

In spite of how much amount, we can say that a large portion of the reason women live longer than men in the present however not as previously, is to have to do with the fact that some important non-biological aspects have changed. What are the factors that are changing? Some are well known and relatively straightforward, like the fact that men smoke more often. Certain 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.

We will now examine the way that female advantages in longevity has changed over time. The following chart shows male and female life expectancies at birth in the US over the period 1790-2014. Two aspects stand out.

First, there's an upward trend. as well as women in the US live much, much longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

And second, there is an ever-widening gap: female advantage in life expectancy used to be quite small, but it grew substantially in the past century.
