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 how has this advantage gotten larger as time passes? We only have a few clues and the evidence is not sufficient to reach an unambiguous conclusion. Although we know that there are biological, psychological and environmental variables which play a significant role in women who live longer than men, we don't know how much each one contributes.

In spite of how much amount of weight, we are aware that at a minimum, the reason women live so much longer than men but not in the past, اوضاع الجماع - visit my web site, is to be due to the fact that a number of key non-biological factors have changed. What are these new factors? Some are well known and relatively straightforward, اوضاع الجماع 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 all countries are over the line of parity diagonally. This means that a newborn girl from every country could expect to live longer than her brothers.

Interestingly, this chart shows that, while the advantage for women exists everywhere, the country-specific differences are huge. In Russia women live 10 years more than males. In Bhutan the difference is less than half a calendar year.

The female advantage in terms of life expectancy was lower in countries with higher incomes that it is today.
Let's examine the way that female advantages in longevity has changed with time. The next chart compares male and female life expectancy at birth in the US between 1790 and 2014. Two distinct features stand out.

There is an upward trend. Women and men living in America are living longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is widening: While the advantage of women in terms of life expectancy was tiny but it has risen significantly over time.

You can check if these principles are also applicable to other countries with information by clicking on the "Change country" option on the chart. This includes the UK, France, and Sweden.
