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. Why do women live longer than men, and why have these advantages gotten bigger over time? There isn't much evidence and we have only limited answers. We are aware that behavioral, biological and environmental factors all contribute to the fact that women are healthier than men; but we don't know exactly how significant the impact of each factor is.

We know that women live longer than males, regardless of weight. However this is not due to the fact that certain non-biological aspects have changed. What are these factors that have changed? Some are well known and اضيق وضعية للجماع (just click the up coming website) 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 men and women. We can see that every country is over the diagonal line of parity. This implies that a baby girl from any country can expect to live longer than her younger brother.

Interestingly, this chart shows that while the female advantage exists everywhere, the cross-country differences are large. In Russia women have an average of 10 years more than males; while in Bhutan the difference is less than half an hour.

Let's look at how the female advantage in life expectancy has changed over time. The chart below illustrates the male and female life expectancy at the birth in the US from 1790 until 2014. Two points stand out.

The first is that there is an upward trend. Men and women in the United States live longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is increasing: While the female advantage in life expectancy was once tiny It has significantly increased in the past.
