Question

Find out in what multiples has population increased in the following timeline and write down your findings.

For example, in the initial phase, the population took 6 centuries (1000 to 1600 A.D.) to double itself. Years (A.D.)

Population of the world approx. (in millions)

Answer 1

From the given timeline, the following findings can be made:

1. From 1000 A.D. to 1600 A.D., population increased from 254 million to 550 million, so it took about 6 centuries to double.
2. From 1600 to 1900, population increased from 550 million to 1,550 million, which is nearly 3 times in about 300 years.
3. From 1900 to 1960, population increased from 1,550 million to 3,100 million, so it doubled in only 60 years.
4. From 1960 to 2000, population increased from 3,100 million to 6,300 million, so it again doubled in about 40 years.
5. By 2010, the world population reached about 7,000 million.

The time required for the world population to double has gradually decreased. This shows that the rate of population growth increased rapidly, especially after 1900.
