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 have a longer life span than men? What is the reason is this difference growing in the past? The evidence is limited and we're only able to provide partial solutions. We know there are biological, behavioral, and environmental factors that play an integral role in the longevity of women over men, we don't know what percentage each factor plays in.

Independently of the exact amount of weight, we are aware that at a minimum, the reason women live longer than men today however not as previously, is to have to do with the fact that a number of key non-biological factors have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Others are more complex. 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, كيفية إقامة علاقة بالصور 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. As we can see, every country is above the diagonal parity line , which means that in every country the newborn girl is likely to live for longer than a newborn boy.1

The chart above shows that, while the advantage for women exists across all countries, the cross-country differences are large. In Russia, women live 10 years more than males. In Bhutan, the difference is less than half a calendar year.

In rich countries the longevity advantage for women used to be smaller
Let's take a look at how the female longevity advantage has changed over time. The chart below shows men and women's life expectancies when they were born in the US from 1790-2014. Two distinct points stand out.

First, كيفية إقامة علاقة بالصور there's an upward trend: Men as well as women in the US have a much longer life span longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is widening: While the female advantage in life expectancy used to be very small, it has increased substantially over time.

By selecting 'Change Country in the chart, you can check that these two points apply to the other countries having available data: Sweden, France and the UK.
