Women live longer than men in 195 countries, and in Russia - by as much as 11 years. Ethiopians born in 2016 can live 19 years longer than their fellow citizens born in 1990, and people in countries with high life expectancy live 34 years longer than those in countries where it is low.
These are just some interesting facts from the BBC Life Expectancy Calculator, based on the Institute for Health Metrics and Evaluation Global Morbidity Survey 2016.
Data for each of the constituent parts of the United Kingdom - England, Scotland, Wales and Northern Ireland - were collected separately.
1. We started to live longer
Average life expectancy in the world has increased by more than seven years since 1990 - on average, it has grown by one year every 3.5 years. People around the world are living longer, including thanks to lower deaths from cardiovascular disease in high-income countries and infant mortality in low-income countries. Improvement in the quality of health care, improved sanitation and new medical advances in the treatment of diseases also played a role.
Healthy life expectancy has also increased by 6.3 years. True, its growth is slowing down.

2. Western countries are leaders in life expectancy
Fourteen of the top 20 countries in terms of life expectancy are in Europe. But the first places were taken by the countries of Southeast Asia - Japan and Singapore, where people on average can live up to 84 years.
As for the UK, England barely made it to the top 20 at 81, Northern Ireland and Wales, where people can live to be around 80, are 32nd and 34th, and Scotland is 42nd out of 198 countries. with a life expectancy of 79 years.
Russia ranks 126th.
3. African countries have the lowest life expectancy
All but two of the 20 lowest life expectancy countries are in Africa.
Children born in 2016 in Lesotho and the Central African Republic, where civil war has taken place, can, on average, live to be 50 - 34 years less than a resident of Japan.
In Afghanistan, decades of war, drought and lawlessness have put the country - the only one of all Asian states - at the bottom of the list with a life expectancy of 58 years.
4. Women live longer than men
Women live longer than men in 195 out of 198 countries, an average of six years. In some countries, the difference reaches 11 years.
As can be seen in the graph below, many countries with large differences in male and female life expectancy are located in Eastern Europe, where relatively low male life expectancy is due to alcoholism and poor working conditions.
There are only three countries where men live longer than women - the Republic of the Congo, Kuwait and Mauritania.
5. In Ethiopia, life expectancy increased by 19 years
Life expectancy has increased in 96% of countries since 1990.
Then the inhabitants of 11 countries, according to statistics, could not expect to live to be 50, and in 2016 all countries crossed this milestone.
Six of the 10 countries with the highest life expectancy gains are in sub-Saharan Africa. In Ethiopia, which had not yet recovered from hunger by 1990, life expectancy was then 47 years. Babies born in 2016 could live 17 years longer, thanks in part to a decrease in respiratory infections and diarrheal diseases like rotavirus and cholera.
6. Life expectancy fell in six countries
Along with the countries with the largest increases in life expectancy, sub-Saharan countries also have four countries where life expectancy has dropped since 1990.
The largest drop in life expectancy was recorded in Lesotho, where, according to UN estimates, one in four citizens is living with HIV. It is the second most prevalent country in the world for HIV.
Children born in neighboring South Africa can live to be 62, two years less than their fellow citizens 25 years older. During these years, the country was severely affected by the HIV epidemic.
7. Difference in neighboring countries
The difference in life expectancy can be local - in some neighboring countries it reaches 20 years.
For example, when crossing the border from China to Afghanistan, the average life expectancy falls by more than 18 years.
In the state of Mali, which has suffered from terrorism for many decades, and this decade from civil unrest, residents can expect to live only up to 62 years. In neighboring Algeria, citizens live up to 77 years.
8. War is devastating
In 2010, Syria ranked 65th in life expectancy and was one of the third countries with the longest life expectancy. During the years of ruthless war, the country was in 142nd place in terms of life expectancy.
At the peak of the 1994 genocide in Rwanda, life expectancy at birth was only 11 years.
9. Like hunger and natural disasters
In 1994-1998, North Korea suffered from devastating hunger, which led to a drop in life expectancy by several years - it was observed until the early 2000s.
More than 200 thousand people died in the earthquake in Haiti. However, life expectancy recovered a year later.
