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 makes women live much longer than men today and why does this benefit increase in the past? The evidence isn’t conclusive and we only have limited answers. We know that behavioral, biological and environmental factors contribute to 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 number of pounds, we know that at least part of the reason women live so much longer than men today, but not in the past, has 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. 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, 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 a newborn girl can expect to live longer than a new boy.1
This chart is interesting in that it shows that the advantage of women exists across all countries, the global differences are significant. In Russia, women live 10 years longer than men. In Bhutan the gap is less than half a calendar year.

The advantage of women in life expectancy was less in the richer countries than it is today.
Let’s see how the female longevity advantage has changed in the course of time. The chart below shows gender-based and female-specific life expectancy at the time of birth in the US in the years 1790 until 2014. Two aspects stand افضل شامبو وبلسم out.
The first is that there is an upward trend. 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.
There is an increasing gap: The female advantage in life expectancy used be very modest, but it grew substantially over the course of the last century.
By selecting ‘Change Country from the chart, check that these two points are also applicable to the other countries with available data: Sweden, France and the UK.
