Why Are Women Living 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. Why do women live so much longer than men today, and افضل شامبو وبلسم why has this advantage increased in the past? The evidence isn't conclusive and we're only able to provide incomplete solutions. Although we know that there are biological, behavioral and environmental variables which play a significant role in women's longevity more than males, we aren't sure the extent to which each factor plays a role.

In spite of how much weight, we know that at least a portion of the reason why women live so much longer than men but not previously, is to relate to the fact that some key non-biological factors have changed. What are these factors that have changed? Some are well known and relatively straightforward, like the fact that men smoke more often. Other are more complicated. 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 افضل شامبو وبلسم survivors, ended up raising women's longevity disproportionately.

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 means that a newborn girl from any country can expect to live longer than her brothers.

This chart shows that, while there is a female advantage throughout the world, the differences between countries can be substantial. In Russia, women live for 10 years longer than males. In Bhutan the gap is just half a year.

The advantage for women in life expectancy was much lower in rich countries that it is today.
We will now examine how the female advantage in longevity has changed with time. The next chart plots male and female life expectancy when they were born in the US during the time period between 1790 and 2014. Two areas stand out.

First, there is an upward trend. Men and women in the United States live longer than they used to 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

And second, there is an ever-widening gap: female advantage in life expectancy used to be very modest but it increased substantially over the course of the last century.
