What are the causes of the population growth?
1. Increase in average age: In the 1950s, a person lived an average of 45 years, while today he lives for more than 71 years. Compared to 1990, the average age of a person has increased by more than 9 years in 2019. The average age in 1990 was 64 years, which has increased to 72.8 years in 2021. However, due to coronavirus, this average age came down to 71 years in 2021. By 2050, it is expected to further increase to 77.2 years
2. Population explosion: In 1950, a woman used to give birth to 5 children on an average. Today every woman in the world is giving birth to an average of 2.5 children. Despite the decrease in the birth rate, the population increased due to population explosion. By the 1980s, an average of 140 million children were born every year. In 2021 itself, 13.4 crore children were born. Between 2040 and 2045, an average of 138 million children are expected to be born every year.
3. Decrease in death rate: The United Nations report shows that both birth rate and death rate are decreasing. In 1990, 93 out of 1,000 children died before completing 5 years of age. Whereas, now out of 1000 children born, 37 of them die before the age of 5 years.
