Why can change in birth rate be slower than change in death rate?

Correct answer: Because it is linked with social norms and family decisions

Answer: B, because birth behaviour is connected with social norms and family decisions. Death rates can sometimes respond relatively quickly to changes in medical care, vaccination, sanitation, nutrition, or disease control. Birth rates are influenced by education, age at marriage, family preferences, cultural expectations, income, women’s opportunities, and access to contraception. These factors often change gradually, so birth-rate change may be slower. A is wrong because birth rates can change. C is wrong because hospitals alone do not decide how many children families have. D does not explain the speed of birth-rate change; land area is not the central social factor here. Memory cue: mortality often responds to services; fertility behaviour often responds to society and decisions.
