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 are more likely to live longer than men? And how the advantage has grown over time? The evidence isn't conclusive and كيفية إقامة علاقة بالصور we only have incomplete answers. We are aware that behavioral, biological and environmental factors play a role in the fact that women are healthier than men; however, we aren't sure what the contribution to each of these variables is.

In spite of the number of pounds, we know that a large portion of the reason women live so much longer than men however not as in the past, has to relate to the fact that a number of fundamental non-biological factors have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Some are more complex. For example, كيفية إقامة علاقة بالصور 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 over the diagonal line of parity. This implies that a baby girl in all countries can expect to live longer than her younger brother.

This graph shows that while there is a female advantage in all countries, the differences across countries can be significant. In Russia women are 10 years older than males; while in Bhutan the difference is just half a year.

The advantage of women in terms of life expectancy was lower in developed countries as compared to the present.
Let's examine how the female longevity advantage has changed over time. The next chart shows the male and female lifespans when they were born in the US over the period 1790-2014. Two things stand out.

First, 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.

The second is that there is an increase in the gap between men and women: female advantage in life expectancy used to be very modest however, it has increased significantly during the last century.

When you click on the option "Change country in the chart, you can check that these two points are also applicable to other countries that have available data: Sweden, France and the UK.
