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 more than men do today and why is this difference growing over time? We only have partial evidence and the evidence isn’t sufficient to draw an absolute conclusion. We know that behavioral, Wikiflight.net/index.php?title=User:ShelliWessel60 biological and environmental factors play a role in the fact that women have longer life spans than men, however, we aren’t sure what the contribution of each factor is.
In spite of the precise amount of weight, we are aware that at a minimum, the reason women live longer than men but not previously, is to do with the fact that several 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. There are other issues that are more intricate. 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 over the line of parity diagonally. This implies that a baby girl in all countries can be expected to live for longer than her younger brother.
This chart shows that, although there is a women’s advantage throughout the world, the differences between countries can be substantial. In Russia women live 10 years longer than men. In Bhutan, the difference is less than half a calendar year.

In the richer countries, the women’s advantage in longevity was not as great.
Let’s look at how female longevity advantage has changed in the course of time. The chart below illustrates the gender-based and female-specific life expectancy at the time of birth in the US between 1790 until 2014. Two things stand out.
The first is that there is an upward trend. Men and women living in America are living longer than they used to 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.
Second, the gap is widening: While the female advantage in life expectancy was once tiny however, it has grown significantly over time.
