Why Women Are More Likely To Live Longer Than Men

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 live longer than men? And why has this advantage gotten larger over time? There isn't much evidence and we're only able to provide some answers. We know that biological, behavioral and environmental factors contribute to the fact that women have longer life spans than men, but we don't know exactly how much the influence of each one of these factors is.

We know that women live longer than males, regardless of weight. But, this is not because of certain non-biological factors have changed. These factors are changing. Some are well known and تحاميل مهبلية (click through the next site) relatively straightforward, like the fact that men smoke more often. Some 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 men and women. It is clear that all countries are above the line of parity diagonally. This means that a newborn girl in every country can expect to live longer than her brother.

This chart illustrates that, while there is a female advantage in all countries, the differences across countries are often significant. In Russia women live 10 years longer than men. In Bhutan the gap is less than half a calendar year.

In rich countries the advantage of women in longevity was not as great.
Let's examine how the female longevity advantage has changed over time. The following chart shows the male and female life expectancy at the time of birth in the US from 1790 to 2014. Two areas stand out.

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

There is an increase in the gap between men and تحاميل مهبلية women: female advantage in life expectancy used to be very small however, it has increased significantly over the course of the last century.

If you select the option "Change country' on the chart, you will be able to confirm that the two points are also applicable to the other countries with available information: Sweden, France and the UK.
