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 reason why women have a longer life span than men? And why has this advantage gotten larger as time passes? The evidence isn’t conclusive and we’re only able to provide incomplete solutions. We are aware that behavioral, biological and environmental factors play a role in the fact that women live longer than men; however, we do not know what the contribution of each factor is.

In spite of the weight, we know that at a minimum, the reason why women live longer than men in the present and not in the past, is to relate to the fact that several significant non-biological elements have changed. These are the factors that are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Other are more complicated. 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 https:/www.thepowerhousegroup.biz/__media__/js/netsoltrademark.php?d=glorynote.com (https://www.livelib.ru/go/https:/www.thepowerhousegroup.biz%2F__media__%2Fjs%2Fnetsoltrademark.php%3Fd%3Dglorynote.com) women. We can see that every country is above the diagonal line of parity. This implies that a baby girl in all countries can be expected to live for longer than her brothers.

The chart below shows that although there is a women’s advantage across all countries, differences between countries could be significant. In Russia women have an average of 10 years more than men. In Bhutan the difference is just half a year.



In the richer countries, the women’s advantage in longevity was smaller

Let’s see how the female longevity advantage has changed over time. The next chart plots male and female life expectancy when they were born in the US over the period 1790-2014. Two aspects 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.

The gap is getting wider: Although the advantage of women in terms of life expectancy was extremely small It has significantly increased in the past.

You can confirm that these are applicable to other countries with data by selecting the “Change country” option in the chart. This includes the UK, France, and Sweden.
