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 are more likely to live longer than men? And how is this difference growing in the past? There is only limited evidence and the evidence isn't sufficient to draw a definitive conclusion. While we are aware that there are behavioral, ماذا يحدث بين الزوجين في الحمام بالصور biological and environmental variables that all play a role in women living longer than men, we do not know what percentage each factor plays in.

In spite of the precise weight, we know that at least a portion of the reason why women live longer than men however not as in the past, is to relate to the fact that some fundamental non-biological factors have changed. These factors 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, ماذا يحدث بين الزوجين في الحمام بالصور 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 implies that a baby girl from any country can expect to live longer than her brother.

This chart illustrates that, even though women enjoy an advantage everywhere, cross-country differences could be significant. In Russia women are 10 years older than males; while in Bhutan the gap is less than half an hour.

The female advantage in life expectancy was much lower in the richer countries than it is now.
Let's look at how female longevity advantage has changed over time. The next chart plots male and female life expectancy when they were born in the US during the time period between 1790 and 2014. Two specific points stand out.

The first is that there is an upward trend. as well as women in the US live a lot, much longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

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

You can confirm that these principles are also applicable to other countries that have data by clicking the "Change country" option in the chart. This includes the UK, France, and Sweden.
