Which of the following is NOT a problem of population census in Nigeria?

Step 1: Analyze the question The question asks which option is NOT a problem of conducting a population census in Nigeria. A census problem is something that makes counting people difficult or inaccurate.

Step 2: Explain the concept A population census is the official counting of people in a country. Problems that affect it are related to the process of counting (logistics, cost, attitude, politics), not the population trends themselves.

Step 3: Evaluate each option

• A. Inadequate transportation: This is a real problem. Poor roads and few vehicles make it hard to reach remote villages and riverine areas.
• B. High birth rate: This is a feature of population growth, not a difficulty in carrying out the census. It affects the size of the population, but it does not obstruct the counting exercise. So it is NOT a census problem.
• C. High cost: This is a real problem. Census requires funds for enumerators, training, materials, and logistics.
• D. Mass illiteracy: This is a real problem. Many people do not understand the purpose of the census, may give wrong information, or may not cooperate. Illiteracy also makes it difficult to recruit enough trained enumerators locally.
• E. Political interest: This is a real problem. In Nigeria, census figures influence revenue allocation and political representation, so there is often manipulation, inflation of figures, and disputes.

Step 4: Answer

Tip: In "which is NOT" questions, ask yourself: "Does this make counting harder, or does it just describe the population?" Census problems are usually the 5 Cs of logistics: cost, communication/transport, cooperation (illiteracy, suspicion), corruption, and controversy (politics). Birth rate is a demographic characteristic, not an obstacle.
