In which situation can concluding population growth by looking only at birth rate be wrong?

Answer and explanation

Correct answer: When out-migration exceeds births

Direct answer: D. Birth rate alone cannot describe total population growth because deaths and migration also matter. If many people leave an area, out-migration can offset births and may make total population growth small or even negative. For example, an area may have many births but lose still more people through out-migration. A is less likely to create this particular error because, with no migration and a known stable death rate, births can be interpreted along with deaths. B provides more complete information, so it helps avoid the error. C improves population measurement and does not itself cause the wrong conclusion. D is correct because large out-migration can change the total population independently of the birth rate. Memory cue: never infer total growth from births alone; check deaths and migration.
