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 have a longer life span than men? And why the advantage has grown in the past? We only have a few clues and the evidence is not sufficient to reach an informed conclusion. We recognize that biological, behavioral and environmental factors all play a role in the fact that women have longer life spans than men, however, we aren't sure how much the influence of each one of these factors is.
We are aware that women are living longer than men, regardless of weight. But this is not due to the fact that certain biological factors have changed. These variables are evolving. Some are well known and Namwon0924.kr/board_ePiF76/1249581 relatively straightforward, like the fact that men smoke more often. Certain 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. We can see 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 brother.
The chart below shows that even though women enjoy an 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 a year.

The advantage for women in terms of life expectancy was lower in countries with higher incomes than it is today.
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 from 1790 to 2014. Two points stand out.
First, there is an upward trend. Men and women in the US live a lot, much longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.
Second, the gap is getting wider: Although the advantage of women in terms of life expectancy was very small but it has risen significantly in the past.
Using the option 'Change country in the chart, you can check that these two points apply to other countries with available information: Sweden, France and the UK.
