Why Women 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's the reason why women live longer than men? Why does this benefit increase in the past? We only have partial evidence and the evidence is not sufficient to draw an absolute conclusion. We know there are behavioral, biological as well as environmental factors that play an integral role in women who live longer than males, we aren't sure what percentage each factor كيفية إقامة علاقة بالصور - glorynote.com - plays in.

In spite of the number of pounds, we know that at least part of the reason why women live so much longer than men and not previously, has to do with the fact that several key non-biological factors 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.

The first chart below shows life expectancy at birth for كيفية إقامة علاقة بالصور men and women. It is clear that every country is over the diagonal line of parity. This implies that a baby girl in every country can be expected to live for longer than her younger brother.

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

We will now examine how the advantage of women in longevity has changed with time. The following chart shows the men and women's life expectancies at the birth in the US between 1790 to 2014. Two things stand out.

First, there is an upward trend. Both men and women in the US have a much longer life span longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

And second, there is an increasing gap: The female advantage in terms of life expectancy used be very modest but it increased substantially over the last century.
