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 have a longer life span than men? And why does this benefit increase as time passes? The evidence is sketchy and we only have some answers. We are aware that behavioral, ابر التخسيس, more info here, biological and environmental factors contribute to the fact that women live longer than men; However, we're not sure how much the influence of each of these factors is.

We have learned that women are living longer than men, regardless of weight. But, this 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. 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, 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 above the line of parity diagonally. This implies that a baby girl from every country could expect to live longer than her older brother.

The chart below shows that although women have an advantage across all countries, differences between countries are often significant. In Russia women live 10 years longer than males; while in Bhutan the difference is just half a year.

In wealthy countries, the longevity advantage for women was previously smaller.
Let's now look at the way that female advantages in terms of longevity has changed over time. The chart below illustrates the gender-based and female-specific life expectancy when they were born in the US during the period 1790 until 2014. Two specific points stand out.

First, there's an upward trend. Men as well as women in the US live much, ابر التخسيس much longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is growing: Although the advantage of women in life expectancy was once extremely small It has significantly increased in the past.

When you click on the option "Change country from the chart, you will be able to confirm that the two points are also applicable to the other countries having available data: Sweden, France and the UK.
