Q. Growth rate of population means ______:
Answer: The difference between birth and death rates
Notes: In demographics and ecology, the “population growth rate” is the rate at which the number of individuals in a population increases in a given time period as a fraction of the initial population. Since Births and deaths are natural causes of population change, the difference between the birth and death rates is the population growth rate. So Population Growth Rate = (Crude Birth Rate) – (Crude Death Rate).
