(a) Outline map of Nigeria showing areas of population density

(b) Three factors responsible for the dense population of the South-East

1. Fertile soils and favourable climate: the region has fertile land and a reliable rainfall that support intensive farming and a dependable food supply, so it can carry a large number of people.
2. Commercial and industrial activity: busy trading and manufacturing centres such as Onitsha, Aba and Nnewi offer wide employment and business opportunities that attract and hold people.
3. Good social amenities and long settlement: the availability of schools, hospitals, water, electricity and a dense network of roads, together with the long history of settled Igbo communities, has encouraged a heavy concentration of people.

(c) Three problems of the dense population of the South-East

1. Overcrowding and housing shortage: too many people compete for limited housing, leading to high rents, congestion and the growth of slums with poor sanitation.
2. Pressure on land and social amenities: farmland becomes fragmented and scarce, and schools, hospitals, water and other services are overstretched, while unemployment rises as jobs cannot match the number of people.
3. Environmental and social strains: heavy population brings traffic congestion, pollution, poor waste disposal, soil erosion from over-use of land, and a higher crime rate.
