Why should time period be the same while comparing population growth rates?
Answer and explanation
Correct answer: So comparison is on the same basis
A population growth rate describes the change in population over a specified period. If the time periods for two places or years differ, comparing their total growth can be misleading; using the same period puts the comparison on an equal basis. Keeping the period the same does not make the death rate zero or stop migration. Exam tip: when comparing growth rates, check both the time period and the population base.
