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 why women have a longer life span than men? And how is this difference growing in the past? There isn't much evidence and we have only limited solutions. We know that biological, behavioral and environmental factors contribute to the fact that women have longer lives than men, however, we aren't sure how significant the impact of each one of these factors is.

In spite of the precise amount of weight, we are aware that at least part of the reason women live longer than men in the present but not in the past, has to do with the fact that certain important non-biological aspects have changed. These factors are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Others are more complex. For تحاميل مهبلية 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 men and تحاميل مهبلية 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 longer than a new boy.1

This chart shows that, while there is a female advantage throughout the world, the differences between countries can be substantial. In Russia women live 10 years longer than men, while in Bhutan the gap is less than half an hour.

In the richer countries, the women's advantage in longevity was not as great.
We will now examine the way that female advantages in longevity has changed with time. The following chart shows male and female life expectancy at birth in the US over the period 1790-2014. Two distinct features stand out.

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

Second, the gap is getting wider: Although the advantage of women in terms of life expectancy was quite small however, it has grown significantly over time.

By selecting 'Change Country from the chart, you will be able to verify that these two points also apply to the other countries having available data: Sweden, France and the UK.
