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 have these advantages gotten bigger in the past? We only have a few clues and the evidence isn't sufficient to support an informed conclusion. Although we know that there are behavioral, biological and environmental factors which all play a part in women who live longer than men, we do not know how much each one contributes.<br><br>It is known that women are living longer than men, regardless of their weight.

As you can see, every country is above the diagonal parity line ; this means in all countries that a baby girl can be expected to live for longer than a newborn boy.1<br><br>The chart above shows that, while the advantage for women exists in all countries, country-specific differences are huge. In Russia women are 10 years older than men. In Bhutan the gap is just half one year.<br><br>__S.17__<br>__S.19__<br>The advantage women had in life expectancy was less in the richer countries than it is now.<br>Let's examine how the gender advantage in longevity has changed over time. The next chart compares male and female life expectancy when they were born in the US during the time period between 1790 and 2014.
