What can be one major reason for decline in death rate in an area?

Answer and explanation

Correct answer: Improvement in health and nutrition

Answer: A, improvement in health and nutrition. The death rate is the number of deaths in a population in relation to its size, usually measured for a particular period. Better medical care, vaccination, sanitation, clean water, disease prevention and adequate nutrition can help people survive illnesses and live longer, so the death rate may decline. A is therefore a valid major reason. B can create water and livelihood problems rather than generally lowering deaths. C does not directly improve survival. D has no direct demographic effect of this kind. Memory cue: healthier people with safer living conditions usually face lower mortality.
