Why women live longer than men?

Danny Arias (2022-04-22)


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? What is the reason the advantage has grown over time? The evidence is sketchy and we have only some answers. We know that biological, behavioral and environmental factors contribute to the fact that women are healthier than men; However, we're not sure how much the influence of each one of these factors is.

In spite of the amount of weight, we are aware that at least part of the reason why women live so much longer than men in the present, but not in the past, has to have to do with the fact that some significant non-biological elements have changed. What are these changing factors? Some are well known and relatively straightforward, like the fact that men smoke more often. Other 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 first chart below shows life expectancy at birth for men and افضل شامبو وبلسم women. As you can see, all countries are above the diagonal line of parity - this means that in all countries baby girls can expect to live longer than a newborn boy.1

It is interesting to note that, while the advantage for women exists across all countries, افضل شامبو وبلسم the difference between countries is huge. In Russia women are 10 years older than males; while in Bhutan the difference is less than half an hour.

The advantage for women in life expectancy was less in rich countries as compared to the present.
We will now examine the way that female advantages in terms of longevity has changed over time. The next chart compares male and female life expectancies at birth in the US between 1790 and 2014. Two areas stand out.

The first is that there is an upward trend: Men and women in the US have a much longer life span longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

There is an ever-widening gap: female advantage in terms of life expectancy used to be very modest but it increased substantially in the past century.
