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 makes women live much longer than men today and why has this advantage increased in the past? We only have partial evidence and the evidence is not strong enough to make an unambiguous conclusion. Although we know that there are biological, psychological and environmental factors that all play a role in women living longer than males, we aren't sure what percentage each factor plays in.

In spite of the amount of weight, we are aware that at least part of the reason women live so much longer than men however not as previously, has to relate to the fact that several 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, زيوت تطويل الشعر 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. As we can see, all countries are above the diagonal line of parity - this means in all countries the newborn girl is likely to live for longer than a newborn boy.1

This chart shows that, while there is a female advantage everywhere, cross-country differences can be substantial. In Russia women have an average of 10 years more than males; while in Bhutan the gap is just half each year.

In the richer countries, the longevity advantage for women used to be smaller
Let's examine how the advantage of women in longevity has changed with time. The next chart shows the male and زيوت تطويل الشعر female lifespans when they were born in the US over the period 1790-2014. Two distinct points stand out.

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

And second, there is an ever-widening gap: female advantage in terms of life expectancy used to be extremely small but it increased substantially over the course of the last century.

Using the option 'Change country by country' in the chart, you can determine if these two points are applicable to the other countries with available data: Sweden, France and the UK.
