Why Women Are More Likely To Live Longer Than Men

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 has this advantage gotten larger as time passes? There is only limited evidence and ابر التخسيس (click to read) the evidence isn't strong enough to make an unambiguous conclusion. We know that behavioral, biological and environmental factors contribute to the fact that women have longer life spans than men, however, we do not know what the contribution of each factor is.

It is known that women live longer than males, regardless of weight. However this isn't due to the fact that certain 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. There are others 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 women. It is clear that every country is above the diagonal line of parity. This means that a newborn girl from every country could be expected to live for ابر التخسيس longer than her brother.

This chart illustrates that, although there is a women's advantage in all countries, the differences across countries could be significant. In Russia, women live 10 years longer than men. In Bhutan, the difference is less that half a year.

In wealthy countries, the female advantage in longevity was smaller
Let's take a look at how the female longevity advantage has changed over time. The next chart compares the life expectancy of males and females when they were born in the US during the time period between 1790 and 2014. Two areas stand out.

The first is that there is an upward trend. Both genders in the United States live longer than they were a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is growing: Although the female advantage in life expectancy used to be very small but it has risen significantly with time.
