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 line of parity - which means that in every country a newborn girl can expect to live longer than a newborn boy.1
This graph shows that even though women enjoy an advantage everywhere, cross-country differences are often significant. In Russia women live for 10 years longer than men. In Bhutan the gap is less that half a year.
__S.17__
__S.19__
The advantage women had in terms of life expectancy was lower in the richer countries than it is now.
Let's now look at how the gender advantage in longevity has changed over time. The next chart shows male and female life expectancies when they were born in the US over the period 1790-2014. Two points stand out.
The first is that there is an upward trend. Men and women in America live 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 getting wider: Although the advantage of women in terms of life expectancy was quite small It has significantly increased in the past.
When you click on the option "Change country in the chart, you will be able to confirm that the two points apply to other countries that have available information: Sweden, France and the UK.
