Question

If natality is just double to the mortality and the number of individuals in a group of population is 1000. Calculate the percentage of growth rate (natural). Assume death rate 60.

• A. 0.05%
• B. 50%
• C. 5%
• D. Between 5-10%

Answer 1

The correct option is D Between 5-10%

The increase in number of individuals in the particular time is termed as natality or birth rate. While individual dying over a time period is termed as mortality or death rate.

In the given example, mortality is 60

So, natality will be 60 + 60 = 120.

Number of individuals in population is 1000

So, natural growth rate = Death rate - Birth rate = 60

So, percentage of growth rate = 60/1000×100 = 6%

Thus, the correct answer is option D.
