Question

Difficulty: MediumPopulation Distribution, Density, and Settlement Patterns in Nigeria

Arrange the following Nigerian states in ascending order of their average population density, from the state with the lowest population density to the state with the highest population density:

  1. 1Niger State
  2. 2Kaduna State
  3. 3Anambra State
  4. 4Lagos State

Answer

The correct sequence from lowest to highest population density is Niger State, Kaduna State, Anambra State, and Lagos State.
Population density in Nigeria increases from the sparsely populated Middle Belt (Niger State) to the moderately populated northern savanna transition zone (Kaduna State), followed by the highly dense South-Eastern agricultural-commercial belt (Anambra State), and culminates in the ultra-dense coastal urban agglomeration of Lagos State.

Step-by-Step Solution

1
Identify the low-density belt state
Niger State belongs to the sparsely populated Middle Belt region, where large land area and historical/physical factors keep population density below 60 persons per square kilometer.
Sparsely populated regions form the baseline for ascending order.
2
Identify the moderate-density belt state
Kaduna State lies in the north-central savanna transition zone with moderate agricultural population density around 120 to 180 persons per square kilometer.
Moderate density areas exceed Middle Belt densities but remain far lower than southern high-density belts.
3
Identify the high rural-urban density belt state
Anambra State is part of the extremely dense South-Eastern belt, where high indigenous population and dense commercial settlements result in over 850 persons per square kilometer.
South-Eastern agricultural and commercial zones rank higher than northern savanna zones in density.
4
Identify the highest density state
Lagos State has Nigeria's smallest land area combined with an immense metropolitan population, creating an extreme density of over 2,500 persons per square kilometer.
Extreme urban concentration makes Lagos State the most densely populated state in Nigeria.
