One of the major forms of migration that tends to create problem in all developing countries is that of___________

Step 1: Analyze the question The question asks which form of migration creates the biggest problems for developing countries like Nigeria, Ghana, and India.

Step 2: Explain the concept Migration is the movement of people from one place to another. It can be classified by direction:

• Rural-urban: from villages to cities
• Rural-rural: from one village or farming area to another
• Urban-rural: from cities back to villages
• Seasonal: temporary movement based on the time of year, such as farm labourers moving during the planting or harvest season

Step 3: Work through the options

• A. Rural-urban migration: In developing countries, many people, especially young adults, leave villages for cities such as Lagos, Abuja, Port Harcourt and Kano in search of jobs, better schools, hospitals, electricity and a "better life." This causes: • Overcrowding and pressure on housing, leading to slums • Strain on water, electricity, transport and health facilities • Urban unemployment and underemployment • Higher crime rates, such as armed robbery and cybercrime • Neglect of agriculture, because rural areas lose their young labour force, which can lower food production and raise food prices

This is the most widespread and serious migration problem in developing countries.

• B. Rural-rural migration: This is usually small in scale and often agricultural, so it rarely causes major national problems.

• C. Urban-rural migration: This is uncommon in developing countries and actually helps relieve urban congestion.

• D. Seasonal migration: This is temporary and generally predictable, so it is not considered a major problem.

Step 4: Answer The correct answer is A. Rural-urban migration.

Step 5: Exam tip When you see "problem" together with "developing countries" in a migration question, think rural-urban drift. Remember it as: "Villages empty, cities overflow." Related JAMB questions often ask about its causes (lack of amenities in rural areas) and its effects (unemployment, congestion, a fall in agricultural output).
