Why is it incomplete to understand population growth only from the national average?

Answer and explanation

Correct answer: Because growth can differ by region and district

Answer: A. A national average is a combined figure calculated for the whole country. It is useful for seeing the broad national pattern, but it can hide differences between states, regions, districts, cities and villages. One area may have rapid growth while another has slow growth or even decline; when these figures are combined, the national average may look moderate. A is correct because regional and district-level information gives a clearer picture for planning schools, hospitals, jobs, housing and other services. B is wrong because national averages are useful as a general summary. C is wrong because local populations certainly exist and are important units of study. D is wrong because population growth is influenced by local birth rates, death rates, migration and social conditions, all of which vary from place to place. Memory cue: an average tells the middle picture, not every local picture.
