If an area has low density but all people are settled along an industrial corridor, what does it indicate?

Correct answer: Linear and economically concentrated density pattern

Correct answer: A, a linear and economically concentrated density pattern. Average density is calculated for the whole area, so it can be low even when people are strongly concentrated in one narrow belt. An industrial corridor usually follows a transport route or connected chain of industrial locations. Employment, factories, markets and services can attract settlement along that line, while other parts of the region remain thinly populated. A is correct because it describes both the shape of settlement—linear—and the reason for concentration—economic activity. B is wrong because people are not spread evenly throughout the area. C is wrong because density can still be calculated using total population and area; the settlement pattern simply needs separate interpretation. D is wrong because industry can influence employment and settlement. Memory cue: low average density can hide high local density.
