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's the reason why women have a longer life span than men? And why has this advantage gotten larger over time? The evidence is sketchy and we're left with only some answers. We know that behavioral, biological and environmental factors all play a role in the fact that women live longer than men; however, we aren't sure how much the influence to each of these variables is.

We are aware that women are living longer than men, regardless of weight. But this isn't because of certain biological or non-biological factors have changed. What are these changing factors? 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 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 تزويد متابعين تيكتوك (https://minecrafting.co.uk) 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 all countries are over the diagonal line of parity. This means that a newborn girl in all countries can anticipate to live longer than her brother.

This chart shows that, although there is a women's advantage across all countries, differences between countries can be substantial. In Russia women have a longer life span than men, while in Bhutan the difference is just half each year.

The advantage of women in life expectancy was less in the richer countries as compared to the present.
Let's now look at how the advantage of women in life expectancy has changed over time. The next chart compares male and female life expectancies at birth in the US during the time period between 1790 and 2014. Two specific points stand out.

First, there is an upward trend. and women in the US have a much longer life span longer today than a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, there's a widening gap: The female advantage in life expectancy used to be quite small but it increased substantially during the last century.

Using the option 'Change country from the chart, you are able to check that these two points apply to other countries that have available data: Sweden, France and the UK.
