Processes of population change are useful for what?

Correct answer: For planning future services

The direct answer is A: processes of population change are useful for planning future services. Births, deaths, and migration change the number and composition of people in a place. By studying these processes, planners can estimate how many schools, hospitals, houses, jobs, transport facilities, and other public services may be needed in the future. A is correct because population information supports practical planning and proper distribution of resources. B is incorrect because rivers do not have a taste that can be studied through population processes. C is incorrect because mountain sounds are unrelated to births, deaths, and migration. D is incorrect because population studies cannot stop weather. A useful memory cue is: population data helps governments plan for people. The exact future cannot always be predicted, but informed planning becomes possible.
