Why are women living longer than men?

Tawanna Cates (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. Why do women live so longer than men, and why does this benefit increase over time? The evidence is limited and we have only incomplete answers. We know that behavioral, biological and environmental factors all contribute to the fact that women live longer than men; but we don't know exactly what the contribution of each one of these factors is.

In spite of how much number of pounds, we know that at a minimum, the reason women live longer than men, but not in the past, تحاميل مهبلية is to have to do with the fact that a number of significant non-biological elements have changed. These are the factors that are changing. Some are well known and relatively straightforward, 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 تحاميل مهبلية (glorynote.com) men and women. As we can see, all countries are above the diagonal line of parity - this means that in all countries the newborn girl is likely to live longer than a new boy.1

This graph shows that although women have an advantage throughout the world, the differences between countries could be significant. In Russia women live 10 years longer than males; while in Bhutan the difference is less than half an hour.

In rich countries the women's advantage in longevity was previously smaller.
We will now examine how the advantage of women in life expectancy has changed over time. The following chart shows male and female life expectancies when they were born in the US from 1790 to 2014. Two distinct points stand out.

First, there is an upward trend. Men and women in the United States live longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The second is that there is an increase in the gap between men and women: female advantage in terms of life expectancy used to be quite small but it increased substantially in the past century.
