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 is the reason women live longer than men? What is the reason has this advantage gotten larger in the past? The evidence is sketchy and we’re left with only limited solutions. While we are aware that there are biological, behavioral as well as environmental factors which all play a part in women who live longer than men, we do not know how much each factor contributes.

In spite of the amount of weight, we are aware that a large portion of the reason women live longer than men and not in the past, is to have to do with the fact that some important non-biological aspects have changed. These are the factors that are changing. 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, ابر التخسيس (link web page) 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. It is clear that all countries are over the diagonal line of parity. This means that a newborn girl from any country can expect to live longer than her brothers.

The chart above shows that although the female advantage exists in all countries, global differences are significant. In Russia, ابر التخسيس women live 10 years more than men. In Bhutan, the difference is just half a year.

The advantage women had in life expectancy was less in the richer countries than it is today.

Let’s look at how the gender advantage in longevity has changed over time. The next chart plots male and female life expectancies at birth in the US during the time period between 1790 and 2014. Two aspects stand out.

First, there is an upward trend. Women and men in America have longer lives than they were 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, there’s an ever-widening gap: female advantage in terms of life expectancy used to be extremely small however it increased dramatically in the past century.
