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 have a longer life span than men? And how is this difference growing over time? There is only limited evidence and the evidence is not strong enough to make an unambiguous conclusion. Although we know that there are biological, behavioral as well as environmental factors that play an integral role in the longevity of women over men, we do not know how much each factor contributes.

In spite of how much weight, we know that at least part of the reason women live longer than men do today however not as previously, has to have to do with the fact that some fundamental non-biological factors have changed. The factors changing are numerous. Some are well known and relatively straightforward, like the fact that men smoke more often. Others 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.

The first chart below shows life expectancy at birth for men and women. As we can see, every country is above the diagonal parity line , which means that in every country a newborn girl can expect to live for longer than a newborn boy.1

This chart shows that, while there is a female advantage across all countries, differences between countries could be significant. In Russia, women live 10 years longer than men. In Bhutan, the difference is less that half a year.

The advantage for women in terms of life expectancy was lower in the richer countries as compared to the present.

We will now examine the way that female advantages in life expectancy has changed over time. The chart below illustrates the gender-based and ماذا يحدث بين الزوجين في الحمام بالصور – just click the following web site – female-specific life expectancy when they were born in the US in the years 1790 until 2014. Two things stand out.

First, there’s an upward trend. as well as women in the US have a much longer life span 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 getting wider: Although the female advantage in life expectancy used to be quite small but it has risen significantly over time.
