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 makes women live longer than men in the present, https://www.cowgirlboss.com/groups/why-women-are-more-likely-to-live-longer-than-men-1187373694/ and why has this advantage increased in the past? The evidence isn’t conclusive and we’re left with only partial answers. We know that behavioral, biological and environmental factors contribute to the fact that women are healthier than men; but we don’t know exactly how significant the impact to each of these variables is.
We are aware that women live longer than men, regardless of their weight. However, this is not because of certain non-biological aspects have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. There are others 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. As you can see, every country is above the diagonal parity line ; it means that in all nations the newborn girl is likely to live for longer than a newborn boy.1
This graph shows that while there is a female advantage across all countries, differences between countries could be significant. In Russia women have a longer life span than men; in Bhutan the gap is just half one year.
In countries with high incomes, the women’s advantage in longevity was smaller
Let’s look at how female longevity advantage has changed over time. The chart below shows gender-based and female-specific life expectancy at the time of birth in the US from 1790-2014. Two distinct features stand out.
There is an upward trend. Men as well as women in the US live a lot, much longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.
The gap is growing: Although the advantage of women in life expectancy was once extremely small however, it has grown significantly in the past.
