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 have these advantages gotten bigger over time? The evidence is sketchy and we have only partial solutions. While we are aware that there are biological, behavioral and environmental variables that all play a role in women living longer than men, we don’t know how much each one contributes.
It is known that women are living longer than men, regardless of weight. But it is not because of 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. Others 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. As we can see, every country is above the diagonal parity line ; it means that in all nations the newborn girl is likely to live longer than a newborn boy.1
The chart above shows that, تحاميل مهبلية while the advantage for women exists in all countries, cross-country differences are large. In Russia women have a longer life span than males; while in Bhutan the difference is just half each year.

In countries with high incomes, the longevity advantage for تحاميل مهبلية women was not as great.
Let’s take a look at how the female longevity advantage has changed in the course of time. The chart below illustrates the male and female life expectancies when they were born in the US from 1790 to 2014. Two things stand out.
There is an upward trend: Men and women in the US are living much, 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 increasing: While the female advantage in life expectancy used to be very small but it has risen significantly over time.
Using the option ‘Change country by country’ in the chart, you will be able to confirm that the two points are applicable to other countries with available information: Sweden, France and the UK.
