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 is the reason women have a longer life span than men? And اضيق وضعية للجماع - address here - why the advantage has grown as time passes? We have only a small amount of evidence and the evidence isn't sufficient to draw an unambiguous conclusion. We know that behavioral, biological and environmental factors all contribute to the fact that women live longer than men; However, we're not sure how significant the impact of each factor is.

In spite of the amount of weight, we are aware that at least part of the reason why women live longer than men today, but not in the past, is to be due to the fact that some significant non-biological elements have changed. These factors are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Others are more complex. 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. We can see that all countries are above the diagonal parity line ; which means that in every country a newborn girl can expect to live longer than a new boy.1

It is interesting to note that the advantage of women exists in all countries, اضيق وضعية للجماع global differences are significant. In Russia, women live 10 years more than males. In Bhutan the gap is less that half a year.

In rich countries the longevity advantage for women used to be smaller
Let's examine how the female longevity advantage has changed over time. The chart below illustrates the men and women's life expectancies at the time of birth in the US from 1790 to 2014. Two aspects stand out.

The first is that there is an upward trend. Both men and women in the US live a lot, much longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

The second is that there is a widening gap: The female advantage in terms of life expectancy used to be very small however, it has increased significantly over the last century.

Using the option 'Change country' on the chart, verify that these two points are applicable to other countries with available information: Sweden, France and the UK.
