If an area has high births but deaths and out-migration are also high, how will you draw the correct conclusion?

Correct answer: Study all adding and reducing processes together

The direct answer is C. A high birth level alone does not prove that the population has increased overall. Births add people, while deaths remove people. Out-migration also removes people from the area, so it must be counted with deaths. If there is in-migration, that must be added as well. The correct conclusion comes from comparing all additions and reductions during the same time period: births + in-migration versus deaths + out-migration. Option C is correct because it uses the complete balance. Option A is wrong because it looks only at the adding process of births. Option B is wrong because it looks only at deaths and ignores births and migration. Option D is wrong because out-migration may strongly change the final result. Memory cue: never call a population “growing” until all four flows have been considered.
