Why Do Women Live Longer Than Men?
We know that women live longer than males, افضل كريم للشعر regardless of weight. However, this is not due to the fact that certain non-biological factors 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, 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 افضل كريم للشعر men and women. As you can see, all countries are above the diagonal parity line ; this means in all countries the newborn girl is likely to live longer than a newborn boy.1
It is interesting to note that, while the advantage for women is present everywhere, cross-country differences are large. In Russia, women live 10 years longer than men. In Bhutan, the difference is only half a year.
The advantage for women in life expectancy was smaller in the richer countries as compared to the present.
Let's take a look at how the female longevity advantage has changed over time. The chart below illustrates the gender-based and female-specific life expectancy when they were born in the US from 1790-2014. Two aspects stand out.
First, there is an upward trend. Men and women in America live longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.
Second, the gap is growing: Although the advantage of women in life expectancy used to be extremely small however, it has grown significantly over time.
