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 more than men do today and how have these advantages gotten bigger in the past? We have only a small amount of evidence and the evidence isn't sufficient to reach an absolute conclusion. While we are aware that there are biological, psychological and environmental variables which play a significant role in the longevity of women over men, we don't know how much each one contributes.

In spite of how much number of pounds, we know that at least part of the reason women live longer than men in the present and not in the past, is to be due to the fact that several key non-biological factors have changed. These factors are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. There are other issues that are more intricate. 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 every country is above the diagonal parity line ; which means that in every country a newborn girl can expect to live longer than a newborn boy.1

This chart is interesting in that it shows that, افضل شامبو وبلسم while the advantage for women exists across all countries, the country-specific differences are huge. In Russia women have a longer life span than males; while in Bhutan the difference is less than half an hour.

In wealthy countries, the female advantage in longevity was previously smaller.
Let's see how the female longevity advantage has changed in the course of time. The following chart shows the men and women's life expectancies at the birth in the US during the period 1790 until 2014. Two aspects stand out.

The first is that there is an upward trend. Both genders in the United States live longer than they used to 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, there's an ever-widening gap: female advantage in life expectancy used be extremely small but it increased substantially over the course of the last century.

If you select the option "Change country in the chart, you are able to determine if these two points are applicable to the other countries with available information: Sweden, France and the UK.
