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 have a longer life span than men? And علامات الحمل بولد why has this advantage gotten larger over time? We only have partial evidence and the evidence isn't sufficient to draw an informed conclusion. We are aware that behavioral, biological and environmental factors all contribute to the fact that women live longer than men; However, we're not sure how much the influence to each of these variables is.

We are aware that women are living longer than males, regardless of weight. However it is not because of certain non-biological aspects have changed. What are the factors that 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, 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 every country is above the diagonal line of parity. This means that a newborn girl from any country can be expected to live for longer than her younger brother.

This graph shows that although women have an advantage everywhere, cross-country differences are often significant. In Russia women live 10 years more than males. In Bhutan the gap is less that half a year.

The advantage women had in terms of life expectancy was lower in developed countries than it is now.
Let's now look at how the female advantage in longevity has changed with time. The following chart shows the male and علامات الحمل بولد (just click the following website) female lifespans when they were born in the US from 1790 to 2014. Two points stand out.

There is an upward trend. Both men and women in the US are living much, much longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

There is an increase in the gap between men and women: female advantage in terms of life expectancy used to be quite small however it increased dramatically over the last century.

When you click on the option "Change country by country' in the chart, you are able to determine if these two points are also applicable to the other countries having available information: Sweden, France and the UK.
