Why Do Women Have Longer Lives Than Men

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 so longer than men and تحاميل مهبلية how does this benefit increase over time? There isn't much evidence and we only have partial solutions. We know there are biological, psychological as well as environmental factors which play a significant role in women's longevity more than men, we don't know what percentage each factor plays in.

It is known that women are living longer than males, regardless of weight. However this isn't due to the fact that certain biological factors have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Some 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 over the line of parity diagonally. This means that a newborn girl from every country could be expected to live for longer than her brothers.

This graph shows that while there is a female advantage everywhere, cross-country differences could be significant. In Russia women are 10 years older than men. In Bhutan the difference is less than half each year.

In rich countries the advantage of women in longevity was smaller
Let's see how the female longevity advantage has changed in the course of time. The chart below shows gender-based and female-specific life expectancy when they were born in the US from 1790 to 2014. Two distinct features stand out.

There is an upward trend. and women in the US have a much longer life span longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is widening: While the advantage of women in life expectancy was once extremely small, it has increased substantially over time.

If you select the option "Change country from the chart, you will be able to determine if these two points are also applicable to the other countries with available data: Sweden, France and the UK.
