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 live longer than men? And how has this advantage gotten larger over time? We only have a few clues and the evidence isn’t strong enough to make an absolute conclusion. We recognize that biological, behavioral and environmental factors all play a role in the fact that women have longer lives than men, however, we do not know how strong the relative contribution of each of these factors is.
We are aware that women live longer than males, regardless of weight. However this is not due to the fact that certain biological factors have changed. These are the factors that are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Other 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 افضل شامبو وبلسم [click through the next internet site] men and women. As we can see, every country is above the diagonal parity line , which means that in every country a newborn girl can expect to live for longer than a new boy.1
The chart above shows that the advantage of women exists across all countries, the global differences are significant. In Russia, women live for 10 years longer than males. In Bhutan the difference is less than half a calendar year.

The advantage women had in life expectancy was less in rich countries than it is now.
Let’s now look at how the advantage of women in life expectancy has changed over time. The following chart shows male and female life expectancy at birth in the US from 1790 to 2014. Two areas stand out.
There is an upward trend. Women and men in the United States live longer than they were a century ago. This is in line with historical increases in life expectancy everywhere in the world.
The gap is widening: While the female advantage in life expectancy was tiny however, it has grown significantly in the past.
