What is the reason women are more likely to live longer than men? Why has this advantage gotten larger as time passes? The evidence is limited and we only have partial solutions. We know that biological, behavioral and environmental factors all play a role in the fact that women are healthier than men; however, we do not know how strong the relative contribution of each factor is.

It is known that women live longer than men, regardless of their weight. But it is not due to the fact that certain non-biological aspects have changed. The factors changing are numerous.

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.

Second, there's an ever-widening gap: female advantage in life expectancy used be very small, but it grew substantially over the last century.
