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 live longer than men in the present and how has this advantage increased over time? There is only limited evidence and the evidence is not strong enough to make an unambiguous conclusion. We know there are biological, behavioral, glorynote.com and environmental factors which play a significant role in women living longer than men, we do not know how much each factor contributes.

What are these factors that have changed? 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.

The advantage of women in terms of life expectancy was lower in rich countries as compared to the present.

Let’s now look at how the advantage of women in longevity has changed over time. The following chart shows the male and female lifespans when they were born in the US over the period 1790-2014. Two areas stand out.

First, there’s an upward trend. Men and women in the US are living much, much longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is growing: Although the female advantage in terms of life expectancy was extremely small however, it has grown significantly with time.
