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 اضيق وضعية للجماع how is this difference growing in the past? The evidence is limited and we’re only able to provide incomplete answers. We know there are biological, behavioral, and environmental factors that play an integral role in women living longer than men, we do not know how much each factor contributes.
In spite of the precise amount, we can say that at least part of the reason women live so much longer than men today but not previously, has to have to do with the fact that certain significant non-biological elements have changed. What are these changing factors? Some are well known and relatively straightforward, like the fact that men smoke more often. Some 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, اضيق وضعية للجماع 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 all countries are over the line of parity diagonally. This means that a newborn girl in every country can expect to live longer than her older brother.
The chart above shows that although the female advantage is present everywhere, cross-country differences are large. In Russia women have a longer life span than men, while in Bhutan the gap is less than half an hour.

The female advantage in life expectancy was smaller in rich countries than it is today.
We will now examine how the female advantage in terms of longevity has changed over time. The chart below shows male and female life expectancy at birth in the US during the period 1790 to 2014. Two things stand out.
First, there’s 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.
Second, the gap is increasing: While the advantage of women in life expectancy was very small but it has risen significantly with time.
By selecting ‘Change Country’ on the chart, you can confirm that the two points are applicable to other countries with available data: Sweden, France and the UK.
