If two states have the same average population density but one state's population is concentrated only in a few towns, which conclusion is correct?

Correct answer: Average density can hide local concentration

Correct answer: B. Average density is calculated for the whole state, so it combines all people and the entire area into one number. That number may be the same for two states even when people are spread relatively evenly in one state and concentrated in a few towns in the other. The second state can therefore have very high local density in towns and very low density elsewhere while still showing the same overall average. B is correct because it recognises the limitation of an average. A is wrong because equal averages do not prove equal internal patterns. C is wrong because density and distribution are related, although average density alone cannot show every detail. D is wrong because town populations are included in population totals. Memory cue: same average does not mean same map.
