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. Why do women live much longer than men today and تحاميل مهبلية how have these advantages gotten bigger in the past? We only have partial evidence and the evidence is not strong enough to make a definitive conclusion. We know there are behavioral, biological as well as environmental factors that play an integral role in the longevity of women over males, we aren't sure how much each one contributes.

Independently of the exact amount of weight, we are aware that at a minimum, the reason why women live so much longer than men today however not as previously, is to relate to the fact that some fundamental non-biological factors have changed. What are these factors that have changed? 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 men and women. As we can see, every country is above the diagonal line of parity - this means that in all countries baby girls can expect to live for longer than a newborn boy.1

It is interesting to note that while the female advantage exists in all countries, تحاميل مهبلية global differences are significant. In Russia women have an average of 10 years more than men, while in Bhutan the difference is just half a year.

In countries with high incomes, the female advantage in longevity was previously smaller.
Let's take a look at how the female longevity advantage has changed over time. The next chart compares the life expectancy of males and females when they were born in the US during the time period between 1790 and 2014. Two things stand out.

There is an upward trend. Women and men in America have longer lives than they used to a century ago. This is in line with historical increases in life expectancy everywhere in the world.

And second, there is a widening gap: The female advantage in terms of life expectancy used be extremely small, but it grew substantially over the last century.

By selecting 'Change Country by country' in the chart, determine if these two points are also applicable to the other countries with available information: Sweden, France and the UK.
