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 and ابر التخسيس why is this difference growing in the past? There is only limited evidence and the evidence is not sufficient to draw a definitive conclusion. We know that biological, behavioral and environmental factors all contribute to the fact that women have longer lives than men, but we don't know exactly how strong the relative contribution of each of these factors is.

It is known that women live longer than men, regardless of weight. But, this is not due to the fact that certain non-biological aspects have changed. What are these new factors? Some are well known and relatively straightforward, like the fact that men smoke more often. Some are more complex. For example, ابر التخسيس 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 means that a newborn girl in every country can be expected to live for longer than her brothers.

The chart below shows that although there is a women's advantage throughout the world, the differences between countries can be significant. In Russia women have a longer life span than men. In Bhutan the difference is just half one year.

In rich countries the longevity advantage for women used to be smaller
We will now examine how the advantage of women in longevity has changed with time. The chart below shows male and female life expectancies at the time of birth in the US between 1790 to 2014. Two areas stand out.

The first is that there is an upward trend. Men and women in America have longer lives than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is getting wider: Although the female advantage in life expectancy used to be tiny, it has increased substantially over time.

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