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 main reason women are more likely to live longer than men? And why does this benefit increase in the past? The evidence is limited and we’re left with only some solutions. We know that behavioral, biological and environmental factors all play a role in the fact that women live longer than men; However, we’re not sure what the contribution of each one of these factors is.
We have learned that women are living longer than men, regardless of their weight. But it is not because of certain non-biological factors have changed. These factors are changing. 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 Naturallawinstitute.com/members/mosemackenzie/activity/173287/ women. As you can see, every country is above the diagonal line of parity – it means that in all nations baby girls can expect to live longer than a newborn boy.1
The chart above shows that, while the advantage for women exists everywhere, the global differences are significant. In Russia women have a longer life span than men. In Bhutan the gap is just half an hour.
In countries with high incomes, the women’s advantage in longevity was not as great.
Let’s look at how the gender advantage in longevity has changed over time. The chart below shows male and female life expectancy at the time of birth in the US between 1790-2014. Two distinct features stand out.
There is an upward trend. Women and men in the United States live longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.
Second, there’s an increase in the gap between men and women: female advantage in life expectancy used to be very modest however it increased dramatically over the course of the last century.
If you select the option «Change country’ on the chart, you can verify that these two points apply to other countries that have available information: Sweden, France and the UK.
