Question

As of this year alone, there have been 301 births and 102 deaths in a population of 1000 giraffes. The number of giraffes who have joined this population are 28 individuals and the number who have left total 39 individuals. What is the growth rate (as a percentage) of this giraffe population?

Answer 1

Given:

Birth rate of Giraffes = 28

Death rate of Giraffes = 39

To find:

Population growth rate of Giraffe population

Formula to be used:

Population growth rate = Birth rate – Death rate

Calculation:

Population growth rate = Birth rate – Death rate

Population growth rate = 28-39

Population growth rate = 11

Percentage of growth rate $=\frac{11}{100}=0.11 \%$

Solution:

From the above calculation it can be inferred that the growth rate of the giraffe population is 0.11%.
