Why Do Women Have Longer Lives 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. Why do women live so more than men do today and why has this advantage increased over time? There isn't much evidence and we're only able to provide partial answers. We know there are biological, behavioral and environmental factors that play an integral role in the longevity of women over males, it isn't clear how much each one contributes.

In spite of how much number of pounds, علامات الحمل بولد we know that at a minimum, the reason women live so much longer than men, but not previously, has to be due to the fact that several fundamental non-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 علامات الحمل بولد women. It is clear that all countries are above the line of parity diagonally. This implies that a baby girl in all countries can be expected to live for longer than her older brother.

This chart is interesting in that it shows that the advantage of women exists in all countries, global differences are significant. In Russia, women live 10 years longer than males. In Bhutan there is a difference of only half a year.

In rich countries the female advantage in longevity was not as great.
Let's look at how the female advantage in terms of longevity has changed over time. The next chart shows the life expectancy of males and females at birth in the US during the time period between 1790 and 2014. Two things stand out.

The first is that there is an upward trend. Men and women in the US have a much longer life span longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, the gap is growing: Although the advantage of women in life expectancy used to be extremely small but it has risen significantly over time.
