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 main reason women are more likely to live longer than men? What is the reason does this benefit increase in the past? There isn't much evidence and we're only able to provide partial solutions. We know that biological, behavioral and environmental factors all contribute to the fact that women live longer than men; However, we're not sure how much the influence of each of these factors is.

We are aware that women live longer than males, افضل شامبو وبلسم regardless of weight. However this is not due to the fact that certain biological factors have changed. What are these factors that have changed? Some are well known and relatively straightforward, like the fact that men smoke more often. Some 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.

Everywhere in the world women tend to live longer than men
The first chart below shows life expectancy at birth for افضل شامبو وبلسم men and women. It is clear that all countries are above the diagonal line of parity. This means that a newborn girl from any country can be expected to live for longer than her older brother.

This chart illustrates that, although there is a women's advantage in all countries, the differences across countries could be significant. In Russia women live 10 years longer than men, while in Bhutan the difference is less than half an hour.

In countries with high incomes, the longevity advantage for women was previously smaller.
Let's examine how the female longevity advantage has changed in the course of time. The following chart shows the life expectancy of males and females when they were born in the US from 1790 to 2014. Two points stand out.

There is an upward trend: Men and women in the US are living much, much 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 advantage of women in life expectancy used to be tiny but it has risen significantly in the past.

If you select the option "Change country by country' in the chart, you will be able to check that these two points also apply to other countries that have available data: Sweden, France and the UK.
