Why Do 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 why does this benefit increase in the past? The evidence is sketchy and we only have partial solutions. While we are aware that there are biological, behavioral and environmental variables that play an integral role in women who live longer than men, we do not know what percentage each factor زيوت تطويل الشعر plays in.

In spite of the number of pounds, we know that at least part of the reason women live so much longer than men today but not previously, has to be due to the fact that a number of significant non-biological elements have changed. What are these factors that have changed? Some are well known and relatively straightforward, like the fact that men smoke more often. Certain 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 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. As you can see, all countries are above the diagonal parity line , which means that in every country baby girls can expect to live for longer than a new boy.1

Interestingly, this chart shows that the advantage of women is present everywhere, زيوت تطويل الشعر country-specific differences are huge. In Russia women have an average of 10 years more than men. In Bhutan the gap is less than half each year.

In countries with high incomes, the advantage of women in longevity was not as great.
Let's take a look at how the female longevity advantage has changed over time. The chart below shows male and female life expectancy when they were born in the US in the years 1790 to 2014. Two things stand out.

The first is that there is an upward trend. Men as well as women in the US live much, much longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is widening: While the female advantage in terms of life expectancy was very small but it has risen significantly with time.

By selecting 'Change Country from the chart, you are able to check that these two points apply to other countries that have available data: Sweden, France and the UK.
