If the birth rate is declining but in-migration is increasing in a region, what is the correct conclusion about total population?

Answer and explanation

Correct answer: Both migration and birth rate must be studied for total population

Answer: B, both migration and birth-related change must be studied, along with deaths. A birth rate indicates how many births occur relative to the population, but total population does not depend on births alone. In-migration adds people, while out-migration removes them; deaths also reduce the population. Thus the broad calculation is total change = births − deaths + in-migration − out-migration. A is wrong because it ignores the increase caused by people entering. C is wrong because no such conclusion follows from the information. D is wrong because deaths remain part of natural change even when migration is important. B is the most complete answer. Memory cue: a low birth rate does not automatically mean a falling total population when migration is positive.
