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. Why do women live longer than men in the present and why has this advantage increased over time? There isn’t much evidence and we have only limited answers. Although we know that there are biological, psychological, and environmental factors that play an integral role in women’s longevity more than men, we don’t know what percentage each factor ماذا يحدث بين الزوجين في الحمام بالصور plays in.
In spite of the precise amount, we can say that at a minimum, the reason why women live longer than men in the present, but not in the past, is to be due to the fact that several key non-biological factors have changed. The factors changing are numerous. 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, ended up raising women’s longevity disproportionately.

Let’s examine how the gender advantage in longevity has changed over time. The chart below shows gender-based and female-specific life expectancy when they were born in the US from 1790 to 2014. Two points stand out.
There is an upward trend. Men as well as women in the US are living much, much longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.
There is a widening gap: The female advantage in life expectancy used to be very small however it increased dramatically over the course of the last century.
