If health improvement reduces death rate while birth rate remains same what will happen to population?

Correct answer: Population may increase

Direct answer: Option D, the population may increase. To understand this, compare the two natural components: births add people and deaths remove people. If the birth rate stays the same while the death rate falls, the number of people being added through births is unchanged, but fewer people are being removed through death. The difference between births and deaths therefore becomes more positive, so natural increase may rise. Option A is wrong because a lower death rate does not by itself reduce population. Option B is wrong because fewer deaths can change the balance even when births remain constant. Option C is wrong because health improvement does not automatically end migration; migration depends on social, economic, environmental, and other conditions. Option D is correct, although the word “may” matters: the final population also depends on in-migration and out-migration. Memory cue: same births plus fewer deaths usually means stronger natural growth.
