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 makes women live longer than men in the present and why has this advantage increased in the past? There isn't much evidence and we have only limited answers. We know that behavioral, biological and environmental factors all play a role in the fact that women have longer lives than men, however, we do not know how much the influence of each of these factors is.

In spite of the precise amount of weight, we are aware that at least a portion of the reason why women live so much longer than men, but not previously, is to do with the fact that a number of important non-biological aspects have changed. These factors are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Certain 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, افضل شامبو وبلسم 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. As you can see, all countries are above the diagonal parity line ; which means that in every country the newborn girl is likely to live for longer than a new boy.1

This chart shows that, although there is a women's advantage everywhere, cross-country differences could be significant. In Russia women have an average of 10 years more than men; in Bhutan the gap is less than half a year.

The advantage for افضل شامبو وبلسم women in life expectancy was less in developed countries than it is today.
Let's examine how the female longevity advantage has changed in the course of time. The next chart compares the life expectancy of males and females at birth in the US over the period 1790-2014. Two specific points stand out.

There is an upward trend. Men and women in America have longer lives than they were a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is getting wider: Although the female advantage in life expectancy was once extremely small however, it has grown significantly with time.

Using the option 'Change country in the chart, you are able to check that these two points are also applicable to the other countries with available information: Sweden, France and the UK.
