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.

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 above the line of parity diagonally. This means that a newborn girl in all countries can be expected to live for longer than her brother.
The chart below shows that even though women enjoy an advantage across all countries, differences between countries are often significant. In Russia, women live 10 years longer than males. In Bhutan, the difference is less that half a year.
__S.17__
__S.19__
In rich countries the female advantage in longevity used to be smaller
Let's look at how female longevity advantage has changed over time. The following chart shows the men and women's life expectancies when they were born in the US in the years 1790-2014. Two distinct points stand out.
First, there's an upward trend. Both 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.
The gap is growing: Although the female advantage in life expectancy was extremely small but it has risen significantly over time.
If you select the option "Change country from the chart, you will be able to verify that these two points also apply to the other countries with available data: Sweden, France and the UK.
