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 longer than men in the present and why has this advantage increased in the past? The evidence is sketchy and we only have incomplete answers. We know that biological, behavioral and environmental factors contribute to the fact that women live longer than men; however, we aren't sure how significant the impact to each of these variables is.<br><br>Independently of the exact amount, we can say that at a minimum, the reason why women live longer than men and not previously, is to have to do with the fact that some important non-biological aspects have changed. The factors changing are numerous. Some are well known and relatively straightforward, like the fact that men smoke more often. Certain are more complicated. For example, there is evidence that in rich countries the female advantage [https://www.purevolume.com/?s=increased increased] in part because infectious diseases used to affect women disproportionately a century ago, [https://glorynote.com/%D8%A7%D9%81%D8%B6%D9%84-%D8%B4%D8%A7%D9%85%D8%A8%D9%88-%D9%88%D8%A8%D9%84%D8%B3%D9%85-%D8%A8%D8%B9%D8%AF-%D8%A7%D9%84%D8%A8%D8%B1%D9%88%D8%AA%D9%8A%D9%86/ افضل شامبو وبلسم] so advances in medicine that reduced the long-term health burden from infectious diseases, especially for survivors, ended up raising women's longevity disproportionately.<br><br>Everywhere in the world women tend to live longer than men<br>The first chart below shows life expectancy at birth for men and women. As we can see, all countries are above the diagonal parity line - this means in all countries that a baby girl can be expected to live longer than a new boy.1<br><br>This graph shows that although women have an advantage in all countries, the differences across countries are often significant. In Russia women live 10 years longer than men; in Bhutan the gap is less than half each year.<br><br>__S.17__<br>__S.19__<br>The advantage of women in life expectancy was smaller in countries with higher incomes that it is today.<br>Let's take a look at how the female longevity advantage has changed over time. The chart below illustrates the male and female life expectancies at the birth in the US in the years 1790 until 2014. Two [https://search.un.org/results.php?query=distinct distinct] points stand out.<br><br>The first is that there is an upward trend. Both men as well as women in the US live a lot, much longer than they did 100 years ago. This is in line with historical increases in life expectancy everywhere in the world.<br><br>And second, there is an increasing gap: The female advantage in life expectancy used to be very modest however it increased dramatically over the course of the last century.<br><br>It is possible to verify that these points are also applicable to other countries that have information by clicking on the "Change country" option in the chart. This includes the UK, France, and Sweden.
