World Population Changes from 1950

 

Population is not constant rather it is dynamic. It changes over time to time. Population changes time to time due to it’s driver- birth, death and migration. Birth and Death are the natural factors after 1950-s humans have controlled birth through the use of contraceptive devices and death through the advancement in the modern health system and technology. Advancement in technology has helped the human to control the natural increase of population but this advancement has caused to increase the migration (Ravenstein) which is the third driver of migration. This migration has helped to change the population in the various countries of the world.

In 1950 AD, the population of the world was only 2.55 billion. In 1960 AD, the population became 3 billion. The main reason in the increase in the population can be credited to the “baby boom.”  The population growth rate in 1960 AD was 1.86% and after 1980 AD, the growth rate of the population began to decrease. In 1999 AD, the population of the world became 6 billion with 1.33% of the growth rate. In 2011, the population of the world became 7 billion with 1.2% of the growth rate. It is estimated that in 2023 AD, the population will attain 8 billion. Although, the population is increasing, the growth rate of the population is decreasing slowly. The reason for this process is due to the increase in use of contraceptive device, increase in celibacy.
