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 main reason women have a longer life span than men? And how is this difference growing in the past? There isn't much evidence and we only have limited answers. We know that biological, ماذا يحدث بين الزوجين في الحمام بالصور [click to find out more] behavioral and environmental factors play a role in the fact that women live longer than men; however, we do not know how much the influence to each of these variables is.

It is known that women live longer than men, regardless of weight. But it is not because of certain 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. Others 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 every country is above the diagonal line of parity. This implies that a baby girl from any country can anticipate to live longer than her younger brother.

The chart above shows that although the female advantage is present everywhere, global differences are significant. In Russia women live 10 years longer than men. In Bhutan the difference is less than half one year.

The advantage women had in life expectancy was less in the richer countries than it is today.
Let's look at the way that female advantages in terms of longevity has changed over time. The following chart shows the men and women's life expectancies at the time of birth in the US in the years 1790 to 2014. Two distinct features stand out.

The first is that there is an upward trend. Both genders in the United States live longer than they were 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

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

By selecting 'Change Country from the chart, determine if these two points apply to other countries with available information: Sweden, France and the UK.
