Concept:Population density is the number of people living per unit area of land.
It is calculated as population divided by land area.
Explanation:In Nigeria, population density varies from state to state.
Anambra State has a very large population living on a relatively small land area.

km2.

Thus, Anambra has the highest population density among the given options.
Answer:Anambra.
