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 why women have a longer life span than men? Why has this advantage gotten larger in the past? There isn't much evidence and we're left with only some solutions. We know that biological, behavioral and environmental factors contribute to the fact that women are healthier than men; however, we do not know how significant the impact of each one of these factors is.

Independently of the exact amount of weight, we are aware that at least part of the reason women live so much longer than men do today and not previously, has to do with the fact that certain significant non-biological elements have changed. These factors are changing. 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 كيفية ممارسة العلاقة الزوجية فى الاسلام women. It is clear that every country is over the diagonal line of parity. This implies that a baby girl in all countries can anticipate to live longer than her brothers.

The chart above shows that although the female advantage is present everywhere, global differences are significant. In Russia women are 10 years older than males; while in Bhutan the difference is just half each year.

Let's examine how the gender advantage in longevity has changed over time. The next chart compares male and female life expectancy at birth in the US between 1790 and 2014. Two points stand out.

First, there is an upward trend. Women and men in America live longer than they used to a century ago. This is in line with historical increases in life expectancy everywhere in the world.

The second is that there is an increase in the gap between men and women: female advantage in terms of life expectancy used to be very modest however it increased dramatically over the last century.
