Revision as of 19:08, 13 January 2022

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 main reason women have a longer life span than men? And how is this difference growing in the past? We have only a small amount of evidence and the evidence isn't sufficient to support an unambiguous conclusion. We recognize that biological, behavioral and environmental factors all contribute to the fact that women are healthier than men; however, we do not know how much the influence of each factor is.

In spite of the number of pounds, we know that at least part of the reason women live longer than men do today and not previously, is to have to do with the fact that several significant non-biological elements have changed. These variables are evolving. Some are well known and relatively straightforward, like the fact that men smoke more often. Other 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 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 كيفية إقامة علاقة بالصور (https://glorynote.com) men and كيفية إقامة علاقة بالصور women. It is clear that every country is over the diagonal line of parity. This means that a newborn girl in all countries can anticipate to live longer than her older brother.

This chart is interesting in that it shows that, while the advantage for women exists everywhere, the difference between countries is huge. In Russia women are 10 years older than men; in Bhutan the gap is just half an hour.

In countries with high incomes, the longevity advantage for women used to be smaller
Let's look at how female longevity advantage has changed in the course of time. The following chart shows the male and female life expectancy when they were born in the US between 1790-2014. Two specific points stand out.

There is an upward trend. Both genders in America live 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 advantage of women in life expectancy used to be tiny however, it has grown significantly over time.

If you select the option "Change country' on the chart, check that these two points apply to other countries that have available information: Sweden, France and the UK.
