Which of these is not a cause of high population growth in Nigeria?

1. Analyze the question The question asks which option is NOT a cause of high population growth. Three options will push the population up, and one will not.

2. Explain the concept Population growth depends on:

• Birth rate (births per 1,000 people)
• Death rate (deaths per 1,000 people)
• Migration

Population grows fast when birth rates are high and death rates are low. Anything that raises births or lowers deaths increases growth. Anything that reduces births slows growth.

3. Step-by-step solution

• A. Improved hygiene: Better sanitation and cleanliness reduce disease and death, so people live longer. This contributes to growth.
• B. Reduction in death rate: Fewer deaths while births continue means the population rises. This contributes to growth.
• C. Family planning unit of Nigeria: Family planning promotes child spacing and limits family size, which lowers birth rates. This works to control population growth, so it is not a cause of high growth.
• D. Increased birth rate: More births directly increase the population. This contributes to growth.

4. Answer The option that is not a cause of high population growth is C. Family planning unit of Nigeria.

5. Exam tip For "which is NOT a cause" questions, first label each option as "pushes up" or "pushes down". Here, A, B and D push the population up, while C is the only one that pushes it down. It is also a good idea to note the word "NOT" before you start, because many students lose marks by picking a cause instead.
