If growth rate suddenly becomes very high in an area, what should administration check first?

Answer and explanation

Correct answer: Changes in birth rate, death rate and migration

Correct answer: A. Population change is explained by three main demographic components: births, deaths, and migration. A sudden increase in growth rate may occur because the birth rate has risen, the death rate has fallen, more people have moved into the area, fewer residents have moved out, or several of these changes have occurred together. Administration should first compare recent and earlier records for all three components and also check whether the data collection method has changed. B, C, and D do not directly measure population change, so they cannot identify its demographic cause. Memory cue: for a sudden population change, check the three doors—births, deaths, and migration.
