According to the latest United Nations (UN) population report, the world population is expected to reach 8 billion by November 15. The report adds that by 2030, India will overtake China as the most populous country in the world. This report was actually published in the month of July, but it will now turn into reality in the coming days.

The United Nations report informed that the world population is expected to reach 8.5 billion in 2030 and increase further to reach 9.7 billion in 2050 and 11.2 billion by 2100. As with any type of projection, there is a degree of uncertainty surrounding these latest demographic data. projections. These figures are based on the medium projection variant, which assumes a decline in fertility for countries where large families are still widespread, as well as a slight increase in fertility in several countries with fewer than two children per woman on average . Prospects for survival should also improve in all countries.

The UN also predicted that by 2050, the United States will remain the third most populous country in the world, behind India and China. Nigeria is expected to be No. 4, followed by Pakistan, Indonesia, Brazil, Congo, Ethiopia and Bangladesh. Russia and Mexico, which are in the top 10 most populous countries in 2022, are projected to lose their ninth and tenth places in 2050. “The population of 61 countries or regions is projected to decline by 1% or more between 2022 and 2050. “, says the report.

“In countries with at least half a million people, the largest relative reductions in population size over this period, with losses of 20% or more, are expected to occur in Bulgaria, Latvia , Lithuania, Serbia and Ukraine.”

In other highlights, the report says global life expectancy has improved by almost 9 years since 1990 – to 72.8 years for babies born in 2019 – and is expected to reach 77.2 years. in 2050 as death rates continue to fall. But in 2021, he said, life expectancy in the world’s poorest countries was seven years behind the global average.
