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 women have a longer life span than men? Why is this difference growing as time passes? The evidence is limited and we have only some answers. We know that biological, behavioral and environmental factors contribute to the fact that women have longer lives than men, However, we're not sure how much the influence of each factor is.

In spite of the precise weight, we know that at a minimum, the reason why women live longer than men in the present however not as previously, has to relate to the fact that several key non-biological factors have changed. What are these new factors? 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.

The advantage for women in life expectancy was smaller in rich countries than it is now.
We will now examine how the female advantage in longevity has changed over time. The chart below shows male and female life expectancies at the time of birth in the US in the years 1790 to 2014. Two areas stand out.

There is an upward trend. Women and men in America live longer than they were 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

There is an ever-widening gap: female advantage in terms of life expectancy used be quite small however it increased dramatically during the last century.

When you click on the option "Change country from the chart, you will be able to determine if these two points are also applicable to other countries that have available information: Sweden, France and the UK.
