This month the population of us humans is going to cross 8 billion. The total population of humans in the 18th century was 8 times less than the number of humans in the world today. The human species originated on Earth two million years ago. Since then the human population in the world has been increasing despite some interruptions in between, in which remarkable population explosion has been seen only after the 19th century.
Rachel Snow of the United Nations Population Fund says that given the increase in the number of people of childbearing age and life expectancy, it has been estimated by the United Nations that the world population can reach 8.5 billion in the year 2030 and Estimating the rate of population growth, it is being told that by the year 2050 this population can reach 9.7 billion and by the 2080s this population can reach 10.5 billion.

According to the United Nations, by the beginning of 2023, India will reach number one in population and China will be at number two. China’s population is 1.4 billion, which will drop to 1.3 billion by 2050. The data also says that by the end of the century China’s population may reach 800 million.
According to the United Nations, in 2021, the average fertility rate was 2.3 children per woman, down from about five in 1950, which will drop to 2.1 by 2050. “We have reached a point in the world where most countries and most people in this world are living in countries that are below replacement fertility capacity,” Snow says.
