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 longer than men? And how has this advantage gotten larger in the past? The evidence is sketchy and we only have limited answers. While we are aware that there are biological, psychological, and environmental factors which play a significant role in women living longer than men, we don’t know the extent to which each factor plays a role.
In spite of how much amount of weight, we are aware that at a minimum, كيفية إقامة علاقة بالصور; glorynote.com, the reason women live so much longer than men in the present and not previously, is to have to do with the fact that some key non-biological factors have changed. What are the factors that are changing? Some are well known and relatively straightforward, like the fact that men smoke more often. There are other issues 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.

The first chart below shows life expectancy at birth for men and women. It is clear that every country is over the diagonal line of parity. This implies that a baby girl from any country can anticipate to live longer than her older brother.
This chart illustrates that, although there is a women’s advantage throughout the world, the differences between countries can be substantial. In Russia women have a longer life span than men. In Bhutan the difference is just half each year.

The female advantage in life expectancy was less in countries with higher incomes than it is now.
Let’s see how the female longevity advantage has changed over time. The chart below illustrates the gender-based and female-specific life expectancy at the time of birth in the US from 1790 to 2014. Two distinct points stand out.
First, there is an upward trend. Men and women in America live longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.
The second is that there is an increase in the gap between men and women: female advantage in life expectancy used be quite small, but it grew substantially over the last century.
