Why Do Women Have Longer Lives 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 is the reason women are more likely to live longer than men? And why does this benefit increase in the past? The evidence is limited and we have only some solutions. We recognize that biological, behavioral and environmental factors play a role in the fact that women have longer lives than men, however, we aren't sure how significant the impact to each of these variables is.

In spite of how much amount of weight, we are aware that at least a portion of the reason women live so much longer than men in the present and not in the past, has to have to do with the fact that a number of key non-biological factors have changed. What are these new factors? Some are well known and relatively straightforward, like the fact that men smoke more often. There are other issues that are more intricate. For كيفية إقامة علاقة بالصور 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 over the diagonal line of parity. This means that a newborn girl in all countries can anticipate to live longer than her older brother.

This chart illustrates that, although there is a women's advantage everywhere, كيفية إقامة علاقة بالصور cross-country differences could be significant. In Russia women are 10 years older than men; in Bhutan the gap is less than half a year.

In wealthy countries, the longevity advantage for women was not as great.
Let's see how the female longevity advantage has changed over time. The chart below shows male and female life expectancies at birth in the US in the years 1790 to 2014. Two areas stand out.

The first is that there is an upward trend: Men as well as women in the US live much, much longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

The gap is increasing: While the advantage of women in life expectancy was very small but it has risen significantly over time.

By selecting 'Change Country by country' in the chart, you are able to verify that these two points also apply to the other countries having available data: Sweden, France and the UK.
