Why can death rate fall rapidly at a certain stage in developing countries?

Answer and explanation

Correct answer: Due to improvements in healthcare, vaccination and nutrition

Correct answer: A. A death rate measures the number of deaths in a population during a given period. In a developing country, death rates can fall quickly when basic living conditions improve. Better hospitals, medicines, clean drinking water, sanitation, vaccination, maternal care and food supply help more people survive diseases and childhood illnesses. Improved nutrition also strengthens the body and reduces the risk of severe illness. This change affects deaths, not births directly. B is wrong because a fall in death rate does not require the birth rate to become zero; births and deaths are separate demographic processes. C is wrong because migration changes where people live, but ending migration does not itself prevent disease or death. D is wrong because the physical area of a country has no direct power to reduce mortality. Memory cue: improved health conditions usually mean fewer deaths.
