Which option gives a wrong conclusion about population change?

Answer and explanation

Correct answer: Population change is decided only by births

The direct answer is A. Population change is not decided by births alone. It is understood by considering three main processes together: births, deaths, and migration. Births add people to a population, while deaths remove people. Migration changes the population of a particular place because people may enter it or leave it. In simple form, actual population change equals births minus deaths plus in-migration minus out-migration. Option A is wrong because it ignores deaths and migration. Option B is correct because each death reduces the number of people living in the area. Option C is correct because in-migration can increase a local population and out-migration can reduce it. Option D is correct because net migration, found by subtracting out-migration from in-migration, affects the final change. Memory cue: remember “births add, deaths subtract, arrivals add, departures subtract.”
