If an area has low density but people are not scattered and are settled in a few small centres, which statement is correct?

Correct answer: Concentrated but overall sparse distribution

Answer: A, concentrated but overall sparse distribution. Average population density is calculated for the whole area, so it can be low even when people live close together in a few small centres. The remaining parts of the area may have very few residents or may be uninhabited. Thus two ideas must be kept separate: density measures the average number of people per unit of area, while distribution or settlement pattern describes how those people are arranged across the area. Option A is correct because the people are clustered in particular centres but the total average for the wider area remains low. B is wrong because uniform distribution would mean people are spread relatively evenly, which the question does not describe. C is wrong because low density is not zero density. D is wrong because the small centres are settlements. Memory cue: a few crowded dots can exist inside a mostly empty map; local concentration and overall low density can occur together.
