Question

Which of the following is used for calculating the rate of population growth?

1)Death rate(d) - birth rate(b)= rate of natural increase(r).
2)Birth rate(b) + death rate(d)= rate of natural increase (r).
3)Death rate(d)+ birth rate m(b)= rate of natural increase (r).
4)Birth rate(b)- death rate(d)= rate of natural increase (r).

Answer 1

Answer:

4

birth rate is more than death rate that means population is growing.

Answer 2

Answer:

The correct answer to this question is option “4”

Explanation:

and it is birth rate (b) – death rate (d) = rate of natural increase(r). If it is positive, then there is a growth in the population, and if the results are negative, there is a decline in population.

Population growth in the world is one of the major concerns of every country in the world, particularly China and India.
