If population is declining in an area but the birth rate is slightly higher than the death rate, what is the most likely cause?

Answer and explanation

Correct answer: Very high emigration

The correct answer is B: very high emigration. First examine natural change: because the birth rate is slightly higher than the death rate, births exceed deaths and natural increase is positive. Yet the total population is declining, so another effect must be removing more people than are being added. Large-scale emigration means many residents leave the area for another place. If the number leaving is greater than the small natural increase, total population falls. Option A, positive net migration, would add people and normally push the population upward. Option C, a higher birth rate, would increase natural growth, not explain the decline. Option D, a lower death rate, would also support growth. Memory cue: total change depends on births − deaths + immigration − emigration.
