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 main reason women have a longer life span than men? And how does this benefit increase as time passes? There is only limited evidence and اوضاع الجماع, glorynote.com, the evidence isn't sufficient to support an absolute conclusion. We recognize that biological, behavioral and environmental factors all play a role in the fact that women have longer life spans than men, however, we do not know what the contribution of each one of these factors is.

We know that women live longer than men, regardless of their weight. But, this is not due to the fact that certain biological factors have changed. These are the factors that are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Others are more complicated. 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.

The first chart below shows life expectancy at birth for men and women. As you can see, every country is above the diagonal line of parity - it means that in all nations that a baby girl can be expected to live longer than a newborn boy.1

This graph shows that although there is a women's advantage in all countries, the differences across countries can be significant. In Russia women are 10 years older than men, while in Bhutan the gap is less than half an hour.

The advantage for women in terms of life expectancy was lower in rich countries than it is today.
Let's now look at how the gender advantage in longevity has changed over time. The following chart shows the life expectancy of males and females when they were born in the US over the period 1790-2014. Two areas stand out.

First, there is an upward trend. Both genders in America live longer than they were a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is increasing: While the advantage of women in life expectancy was once very small, it has increased substantially over time.

By selecting 'Change Country in the chart, you are able to determine if these two points apply to the other countries with available data: Sweden, France and the UK.
