A report published by the UN Population Division on Monday, according to a UN study published by the UN, has suggested that the life expectancy of the world’s population will decrease from 72.8 years in 2019 to 71 years by 2021, down from 72.8 years in the year 2018
World Population Prospects 2022: There has been an increase of nearly nine years in life expectancy at birth between 1990 and 2019 as reported in the World Population Prospects 2022: Summary of Results report.
However, this has been in the face of Covid, which wiped out some of the gains between 1990 and 2019. It is estimated that the life expectancy of humans will reach 77.2 years around the world by the year 2050.
It was found in the report that in 2021, women lived an average of 73.8 years longer than men (68.4 years), with one-third as long as each other. It has been observed that women in virtually any region and country worldwide have a survival advantage over men.
Across Latin America and the Caribbean, women have a seven-year advantage in the age at birth at which they can expect to live, while in Australia and New Zealand, they have a two-year advantage.
Reports from some regions indicated that there has been an increase in the gap between the life expectancy of men and women over the past three decades and that the gap has widened a little in some regions.
Nevertheless, the gap in life expectancy between the sexes over the last three decades has narrowed in some areas compared to the gap in life expectancy at birth between both sexes.
Among the different regions, Australia and New Zealand are ranked at the top of the list for life expectancy at birth (84.2). Among the sub-Saharan African countries, Sub-Saharan Africa ranks last with a life expectancy of 59.7 years.
According to the data, the average life expectancy in the Middle East, Pakistan, East Africa, and North Africa was 72.1 years, that in North Africa and West Asia was 72.1 years, and that in the Southern Hemisphere was 72.2 years.
Additionally, the report highlights several differences between countries regarding life expectancy.
Life expectancy at birth differed by 33.4 years between the countries with the highest and the lowest life expectancies at birth in 2021, based on the difference between each country’s life expectancy at birth.
Summary
The following are the top 10 countries with the highest life expectancy after birth in 2022 among those having populations of at least half a million people: Australia, Hong Kong SAR, Macau SAR in China, and Japan.
Their life expectancies have reached almost 85 years in these countries. Considering the context described above, Nigeria, the Central African Republic, Chad, Lesotho, and the Central African Republic will be the countries with the lowest life expectancy at birth in 2021, with values below 54 years at birth,” according to the World Bank report.
A study published in 2008 estimates that there is a likelihood of a further widening of the life expectancy gap between countries with the highest and lowest life expectancies.
During the next few decades, survival rates will continue to rise, which means that countries’ and regions’ life expectancy differences will be more negligible and a larger gap will exist between countries with the highest life expectancy at birth and those with the lowest.
By 2050, the gap between countries with the lowest and the highest scores is expected to be 31 8 years due to further increases in survival.
Sub-Saharan Africa, in 2021, has a 20 times higher probability of dying before the age of five than a child born in Australia or New Zealand. An analysis of the under-five mortality rate shows that both countries have the lowest and highest life expectancies at birth.
The difference is primarily caused by differences in the mortality rate of children under five, which is the probability that a child is between birth and five years old at the time of delivery.
