Population growth information is useful for what?

Correct answer: Development and resource planning

Direct answer: A, development and resource planning. Population information helps planners estimate how many people may need food, water, houses, schools, hospitals, transport, employment, and other facilities. A sensible process is to find the present population, examine its rate of increase or decrease, estimate likely future needs, and then plan resources accordingly. Option A is correct because development should match the number and needs of people. Option B is wrong: population data may be shown in a graph or map, but drawing is only a method of presentation, not its main purpose. Option C is wrong because singing has no direct role in allocating resources. Option D is wrong because colour selection is not the purpose of demographic information. Memory cue: population data helps answer “how many people, what needs, and where?”
