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 women are more likely to live longer than men? What is the reason is this difference growing over time? There isn't much evidence and اضيق وضعية للجماع we're left with only some solutions. We are aware that behavioral, biological and environmental factors all play a role in the fact that women live longer than men; but we don't know exactly what the contribution of each factor is.

We know that women are living longer than males, regardless of weight. However it is not due to the fact that certain non-biological aspects have changed. What are these factors that have changed?

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 - which means that in every country the newborn girl is likely to live for longer than a new boy.1

The chart below shows that while there is a female advantage in all countries, the differences across countries are often significant. In Russia women have a longer life span than men, while in Bhutan the gap is less than half a year.

The advantage for women in terms of life expectancy was lower in the richer countries as compared to the present.
Let's examine how the female longevity advantage has changed in the course of time. The next chart shows the male and female lifespans at birth in the US between 1790 and 2014. Two things stand out.

There is an upward trend. Men and women in America have longer lives than they used to 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, اضيق وضعية للجماع there's an ever-widening gap: female advantage in terms of life expectancy used to be extremely small, but it grew substantially during the last century.
