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 main reason women have a longer life span than men? Why is this difference growing as time passes? The evidence is sketchy and we're left with only incomplete answers. We know that biological, behavioral and ابر التخسيس environmental factors all play a role in the fact that women have longer life spans than men, but we don't know exactly how significant the impact of each one of these factors is.

We know that women live longer than men, regardless of their weight. However it is not because of certain biological factors have changed. The factors changing are numerous. Some are well known and relatively straightforward, like the fact that men smoke more often. Certain 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 ابر التخسيس men and women. As we can see, all countries are above the diagonal parity line ; which means that in every country that a baby girl can be expected to live longer than a new boy.1

The chart above shows that while the female advantage exists in all countries, cross-country differences are large. In Russia women live 10 years longer than men; in Bhutan the difference is less than half each year.

The advantage for women in life expectancy was less in developed countries that it is today.
Let's look at how the gender advantage in terms of longevity has changed over time. The chart below illustrates the male and female life expectancy at birth in the US between 1790 until 2014. Two specific points stand out.

There is an upward trend. Men and women in America live longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

There is an ever-widening gap: female advantage in life expectancy used to be very small but it increased substantially over the last century.
