With a billion people added in the past 12 years, the world’s population reached eight billion as of November 15. The report released by the United Nations stated that the world’s population has reached eight billion. The report cited an increase in life expectancy and a decrease in child mortality as the main reasons for population growth. It is estimated that it will take 12 years for the world’s population to grow by one billion and about 15 years to add another billion. The report claims that the world’s population will reach 8.5 billion in 2030. Likewise, it is estimated that the world’s population will reach 9.7 billion by 2050, and 10.4 billion by 2100.
Fertility rates have fallen in many countries. However, the report also shows that the birth rate is increasing in countries with low per capital income. The growth of the world’s population is continuing even during the Covid-19 epidemic and it is estimated that the population has increased by 16 million to 28 million during this period. This number is about 20 percent of the deaths during this period.
By 2022, Asia is the second most population region. The United Nations has estimated that India will overtake China as the world’s most populous country in 2023. Currently, China has a population of 1.44 billion and India has a population of 1.39 billion.
