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 is the reason women live more than men do today, and صبغ الشعر بالاسود why have these advantages gotten bigger over time? There is only limited evidence and the evidence is not sufficient to support an absolute conclusion. While we are aware that there are biological, behavioral, and environmental factors which all play a part in women who live longer than males, we aren’t sure how much each one contributes.
It is known that women are living longer than men, regardless of weight. But it is not because of certain non-biological aspects have changed. These are the factors that are changing. Some are well known and 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.
Everywhere in the world women tend to live longer than men
The first chart below shows life expectancy at birth for men and women. It is clear that all countries are above the diagonal line of parity. This implies that a baby girl in every country can anticipate to live longer than her younger brother.
This graph shows that while there is a female advantage in all countries, the differences across countries are often significant. In Russia, women live for 10 years longer than males. In Bhutan, the difference is just half a year.
The advantage for women in life expectancy was less in countries with higher incomes than it is now.
Let’s see how the female longevity advantage has changed in the course of time. The chart below illustrates the gender-based and female-specific life expectancy at the birth in the US during the period 1790 until 2014. Two specific points stand out.
There is an upward trend. Men and women in the United States live longer than they used to a century 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 terms of life expectancy was very small It has significantly increased in the past.
