1 year agoEverywhere 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 longer than men in the present, and why has this advantage increased in the past? We have only a small amount of evidence and the evidence is not sufficient to support an unambiguous conclusion. We know that behavioral, biological and environmental factors play a role in the fact that women have longer lives than men, However, we're not sure how significant the impact of each of these factors is. In spite of the precise weight, we know that at least part of the reason why women live longer than men in the present however not as previously, has to have to do with the fact that a number of significant non-biological elements have changed. These factors are changing. Some are well known and relatively straightforward, like the fact that men smoke more often. Certain are more complicated. For صبغ الشعر بالاسود 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, صبغ الشعر بالاسود 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 every country is over the line of parity diagonally. This means that a newborn girl from any country can expect to live longer than her brother. The chart above shows that while the female advantage is present everywhere, global differences are significant. In Russia women live 10 years more than men. In Bhutan, the difference is only half a year. __S.17__ __S.19__ In the richer countries, the longevity advantage for women was previously smaller. Let's examine how the female longevity advantage has changed over time. The next chart shows the male and female lifespans when they were born in the US between 1790 and 2014. Two points stand out. First, there is an upward trend. Women and men in the United States live longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world. There is an increasing gap: The female advantage in terms of life expectancy used to be very small but it increased substantially over the course of the last century. It is possible to verify that these points are also applicable to other countries with information by clicking on the "Change country" option on the chart. This includes the UK, France, and Sweden.
