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 have a longer life span than men? What is the reason has this advantage gotten larger over time? There is only limited evidence and the evidence is not sufficient to support an informed conclusion. We know that behavioral, زيوت تطويل الشعر (https://glorynote.com/%D8%B2%D9%8A%D9%88%D8%AA-%D8%AA%D8%B7%D9%88%D9%8A%D9%84-%D8%A7%D9%84%D8%B4%D8%B9%D8%B1) biological and environmental factors contribute to the fact that women have longer life spans than men, however, we aren't sure how strong the relative contribution of each factor is.

We know that women are living longer than males, regardless of weight. But this isn't due to the fact that certain non-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. Others are more complex. For زيوت تطويل الشعر 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 every country is above the line of parity diagonally. This means that a newborn girl in every country can expect to live longer than her older brother.

This chart is interesting in that it shows that while the female advantage exists in all countries, country-specific differences are huge. In Russia, women live 10 years more than men. In Bhutan the gap is less than half a calendar year.

In the richer countries, the women's advantage in longevity was not as great.
Let's see how the female longevity advantage has changed over time. The next chart plots male and female life expectancies at birth in the US from 1790 to 2014. Two aspects stand out.

First, there is an upward trend. Men and women in America have longer lives than they used to 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, there's an ever-widening gap: female advantage in life expectancy used be very modest however it increased dramatically over the course of the last century.

It is possible to verify that these points are also applicable to other countries with data by clicking on the "Change country" option on the chart. This includes the UK, France, and Sweden.
