Why can equal absolute growth be misleading while comparing population growth rates?

Answer and explanation

Correct answer: क्योंकि आधार जनसंख्या अलग हो सकती है

Direct answer: A is correct. Absolute growth is the actual number added to a population, while the growth rate usually expresses that addition as a percentage of the starting or base population. The same numerical increase can therefore represent very different rates. For example, an addition of 10,000 people is 10 percent of a base of 100,000 but only 1 percent of a base of 1,000,000. If planners compare only the number added, they may wrongly conclude that the two populations are growing equally fast. A is correct because different base populations change the percentage interpretation. B is wrong because a census or population estimate can be associated with specific years. C is wrong because birth rates need not be equal. D is wrong because mortality is relevant to population change. Memory cue: percentage growth always needs a denominator—the base population.
