Why do women live longer than men?

Iva Unger (2022-04-20)

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 so longer than men and why has this advantage increased over time? The evidence isn't conclusive and we're left with only incomplete answers. Although we know that there are biological, behavioral and environmental variables that play an integral role in women's longevity more than males, it isn't clear what percentage each factor plays in.

It is known that women are living longer than males, افضل كريم للشعر regardless of weight. However this is not due to the fact that certain biological factors have changed. These variables are evolving. 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.

Everywhere in the world women tend to live longer than men
The first chart below shows life expectancy at birth for افضل كريم للشعر men and women. As we can see, all countries are above the diagonal parity line , this means that in all countries a newborn girl can expect to live for longer than a new boy.1

This chart shows that, even though women enjoy an advantage across all countries, differences between countries could be significant. In Russia women have an average of 10 years more than men, while in Bhutan the gap is less than half an hour.

In the richer countries, the women's advantage in longevity was smaller
Let's now look at how the female advantage in terms of longevity has changed over time. The chart below shows men and women's life expectancies at the birth in the US during the period 1790 until 2014. Two things stand out.

First, there is an upward trend: Men as well as women in the US have a much longer life span longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, there's a widening gap: The female advantage in terms of life expectancy used be very small but it increased substantially during the last century.
