Why do women 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 women live longer than men? What is the reason does this benefit increase in the past? We have only a small amount of evidence and ابر التخسيس (https://glorynote.com/%D8%A7%D8%A8%D8%B1-%D8%A7%D9%84%D8%AA%D8%AE%D8%B3%D9%8A%D8%B3) the evidence is not sufficient to support an informed conclusion. We are aware that behavioral, biological and environmental factors contribute to the fact that women have longer lives than men, however, we do not know what the contribution of each of these factors is.
It is known that women live longer than males, regardless of weight. However this isn’t due to the fact that certain non-biological aspects have changed. What are these changing factors? 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, especially for survivors, ابر التخسيس 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 you can see, all countries are above the diagonal parity line – it means that in all nations baby girls can expect to live longer than a newborn boy.1
Interestingly, this chart shows that the advantage of women exists in all countries, country-specific differences are huge. In Russia women live 10 years longer than males; while in Bhutan the difference is less than half one year.

The female advantage in life expectancy was much lower in rich countries than it is today.
Let’s examine how the female longevity advantage has changed over time. The following chart shows the male and female lifespans at birth in the US from 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.
And second, there is an increasing gap: The female advantage in terms of life expectancy used be very small however it increased dramatically during the last century.
If you select the option “Change country from the chart, you can confirm that the two points apply to the other countries with available data: Sweden, France and the UK.
