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 تحاميل مهبلية (other) why does this benefit increase in the past? The evidence isn't conclusive and we have only incomplete solutions. We recognize that biological, behavioral and environmental factors play a role in the fact that women have longer life spans than men, but we don't know exactly what the contribution of each of these factors is.

In spite of the precise weight, we know that a large portion of the reason women live so much longer than men in the present but not in the past, has to be due to the fact that several important non-biological aspects have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. There are other issues 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.

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, all countries are above the diagonal line of parity - this means in all countries baby girls can expect to live longer than a newborn boy.1

This chart shows that, while there is a female advantage throughout the world, the differences between countries are often significant. In Russia women live for تحاميل مهبلية 10 years longer than men. In Bhutan the gap is less that half a year.

The female advantage in life expectancy was smaller in developed countries than it is today.
Let's now look at the way that female advantages in longevity has changed over time. The following chart shows the gender-based and female-specific life expectancy when they were born in the US from 1790 until 2014. Two distinct points stand out.

The first is that there is an upward trend. and women in the US have a much longer life span longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, there's a widening gap: The female advantage in life expectancy used to be very small, but it grew substantially during the last century.

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