Why women are more likely to live longer than men?

Leandro Tilton (2022-04-20)


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. Why do women live more than men do today, and why have these advantages gotten bigger over time? We only have partial evidence and افضل شامبو وبلسم the evidence is not sufficient to support an unambiguous conclusion. Although we know that there are biological, behavioral and environmental factors which play a significant role in women living longer than men, we don't know how much each factor contributes.

We have learned that women are living longer than men, regardless of their weight. But, this is not due to the fact that certain biological or non-biological factors have changed. What are the factors that are changing? 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, افضل شامبو وبلسم 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, all countries are above the diagonal parity line ; this means in all countries that a baby girl can be expected to live for longer than a new boy.1

The chart below shows that even though women enjoy an advantage throughout the world, the differences between countries could be significant. In Russia women are 10 years older than men, while in Bhutan the gap is less than half each year.

The advantage for women in life expectancy was smaller in the richer countries that it is today.
Let's take a look at how the female longevity advantage has changed in the course of time. The chart below shows men and women's life expectancies at the time of birth in the US in the years 1790 to 2014. Two areas stand out.

First, there's an upward trend: Men and 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 getting wider: Although the advantage of women in terms of life expectancy was tiny but it has risen significantly with time.

By selecting 'Change Country from the chart, determine if these two points are applicable to other countries that have available information: Sweden, France and the UK.
