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 the advantage has grown in the past? We only have a few clues and the evidence is not sufficient to reach an absolute conclusion.

Let's look at how female longevity advantage has changed in the course of time. The chart below illustrates the gender-based and female-specific life expectancy at the birth in the US between 1790 to 2014. Two distinct features stand out.

First, صبغ الشعر بالاسود there is an upward trend. and women in the US live a lot, much longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.
