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 women live longer than men? And how has this advantage gotten larger over time? We only have a few clues and the evidence is not strong enough to make an informed conclusion. While we are aware that there are biological, psychological, and environmental factors which play a significant role in the longevity of women over men, we don't know what percentage each factor plays in.

In spite of the precise number of pounds, ابر التخسيس we know that a large portion of the reason women live longer than men and not previously, is to relate to the fact that certain significant non-biological elements have changed. What are the factors that are changing? Some are well known and 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. We can see that all countries are over the diagonal line of parity. This means that a newborn girl in every country can expect to live longer than her brother.

This chart illustrates that, although there is a women's advantage in all countries, the differences across countries can be significant. In Russia, ابر التخسيس women live for 10 years longer than men. In Bhutan there is a difference of less that half a year.

The female advantage in life expectancy was less in countries with higher incomes than it is today.
Let's examine how the gender advantage in terms of longevity has changed over time. The chart below illustrates the gender-based and female-specific life expectancy at the time of birth in the US from 1790 until 2014. Two areas stand out.

First, there is an upward trend. as well as women in the US are living much, much 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 female advantage in life expectancy used to be very small It has significantly increased over time.

By selecting 'Change Country by country' in the chart, you are able to confirm that the two points also apply to the other countries with available information: Sweden, France and the UK.
