Which option is a balanced evaluation of population growth?

Correct answer: Number, rate, structure, migration and resources should all be studied

Direct answer: C is correct. A balanced study uses several connected measures. Total population shows the size of the population; the growth rate shows how quickly it is changing; age structure shows the share of children, working-age people and older people; migration shows movement into or out of a place; and resources indicate whether food, water, housing, education, health care and employment can meet needs. C is correct because it considers size, speed, composition, movement and carrying capacity together. A is wrong because total number does not show the rate or age structure. B is wrong because birth rate alone ignores deaths, migration and population composition. D is wrong because map colours are only a way of presenting information and cannot replace analysis. Memory cue: good population analysis asks “how many, how fast, who, where from, and what resources?”
