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 main reason women are more likely to live longer than men? Why is this difference growing in the past? There is only limited evidence and the evidence is not sufficient to support a definitive conclusion. We know that biological, behavioral and environmental factors all play a role in the fact that women have longer life spans than men, However, we're not sure how much the influence of each of these factors is.

In spite of the precise amount, we can say that at a minimum, the reason women live longer than men however not as previously, is to be due to the fact that several significant non-biological elements have changed. What are these new factors? 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 Classicalmusicmp3freedownload.com/ja/index.php?title=Why_Do_Women_Live_Longer_Than_Men (www.rlfried.net blog article) 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 men and women. We can see that every country is above the line of parity diagonally. This means that a newborn girl from any country can be expected to live for longer than her younger brother.

The chart above shows that, while the advantage for women is present everywhere, cross-country differences are large. In Russia women live 10 years more than males. In Bhutan, the difference is just half a year.

The advantage women had in life expectancy was less in rich countries that it is today.
Let's take a look at how the female longevity advantage has changed in the course of time. The chart below illustrates the men and women's life expectancies at the birth in the US during the period 1790 to 2014. Two things stand out.

First, there is an upward trend. Women and men in the United States live longer than they did 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 grew substantially over the course of the last century.

If you select the option "Change country in the chart, you will be able to confirm that the two points are also applicable to the other countries having available information: Sweden, France and the UK.
