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’s the reason why women live longer than men? What is the reason does this benefit increase in the past? The evidence is sketchy and we’re left with only partial solutions. While we are aware that there are biological, behavioral and environmental variables which play a significant role in women who live longer than men, we don’t know the extent to which each factor plays a role.

We are aware that women are living longer than men, regardless of weight. But it is not due to the fact that certain biological factors have changed. What are these new 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.

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 every country is above the line of parity diagonally. This implies that a baby girl from any country can anticipate to live longer than her brother.

The chart below shows that even though women enjoy an advantage in all countries, the differences across countries can be substantial. In Russia women live 10 years longer than men. In Bhutan the gap is less that half a year.



The advantage women had in life expectancy was smaller in countries with higher incomes as compared to the present.

Let’s take a look at how the female longevity advantage has changed over time. The chart below shows male and Www.20-go-gaming.de/index.php?site=profile&id=94566 female life expectancies at birth in the US during the period 1790 to 2014. Two specific points stand out.

There is an upward trend. Both genders in America live longer than they were 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

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