Why may population growth initially increase when improved health services reduce the death rate?

Answer and explanation

Correct answer: Because fewer people die while the birth rate may remain high for some time

Population change depends partly on the balance between births and deaths. When health care, vaccination, sanitation, and nutrition improve, fewer people may die. If birth rates remain high for some time, births outnumber deaths by a larger margin, so natural increase and population growth rise initially.

For example, if births remain at 30 per thousand people while deaths fall from 20 to 10 per thousand, the natural increase rises from 10 to 20 per thousand. The later effect may differ if fertility also declines, but the question asks about the initial period. Therefore option A is correct. Health services do not stop births or automatically remove migration.
