Why Women Are More Likely To Live Longer 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's the main reason women live longer than men? Why has this advantage gotten larger as time passes? There isn't much evidence and we're left with only some solutions. Although we know that there are behavioral, biological as well as environmental factors which play a significant role in women who live longer than males, it isn't clear the extent to which each factor plays a role.

In spite of how much number of pounds, we know that at a minimum, the reason why women live so much longer than men today and not previously, is to have to do with the fact that several significant non-biological elements have changed. The factors changing are numerous. 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, ابر التخسيس so advances in medicine that reduced the long-term health burden from infectious diseases, especially for ابر التخسيس (glorynote.com) 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. We can see that every country is above the diagonal parity line , which means that in every country a newborn girl can expect to live for longer than a new boy.1

Interestingly, this chart shows that although the female advantage exists across all countries, the country-specific differences are huge. In Russia women live for 10 years longer than men. In Bhutan there is a difference of just half a year.

In countries with high incomes, the longevity advantage for women used to be smaller
Let's see how the female longevity advantage has changed in the course of time. The next chart compares the life expectancy of males and females when they were born in the US during the time period between 1790 and 2014. Two distinct features stand out.

The first is that there is an upward trend. as well as women in the US have a much longer life span longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is growing: Although the female advantage in life expectancy was once quite small however, it has grown significantly in the past.

Using the option 'Change country in the chart, you are able to verify that these two points are also applicable to the other countries with available data: Sweden, France and the UK.
