In which situation will data on birth, death and migration be most useful for policy making?

Answer and explanation

Correct answer: When future needs for schools, health services, housing and employment must be estimated

The direct answer is A. Birth, death and migration data together show how a population is changing. Births and deaths help indicate natural increase or decrease, while migration shows how many people enter or leave and how population is redistributed between places. Step 1: use past and present records to identify trends. Step 2: estimate the likely number and location of people in the future. Step 3: use the estimate to plan schools, hospitals, housing, water supply, transport and employment opportunities. B requires agricultural and weather data, not mainly demographic data. C requires transport and road-safety considerations. D requires scientific water testing. A is correct because public policy must match the number, distribution and needs of people. Memory cue: demographic data support planning for people; physical or agricultural questions need different data.
