Question

If birth rate is 100, death rate is 10 and the number of individuals in the population group is 1000, then what will be the percentage of natural growth rate?

• A. 0.09%
• B. 9.0%
• C. 0.9%
• D. 90%

Answer 1

The correct option is B 9.0%

The increase in number of individuals at a particular time period is termed as “birth rate” or “natality”, while the individuals dying over a time period is known as “mortality” or “death rate”.

Birth rate – 100

Death rate -10

Number of individuals in a population – 1000

Natural growth rate = 100 -10 = 90

So, percentage of growth rate = 90/1000 x 100 = 9%
