In this lesson you will:

Calculate population density.
Explain push and pull factors.
Describe effects of migration.

Distribution and Density

Population density = population ÷ area in km². Nigeria's population is unevenly distributed: dense in the south-west and around cities, sparse in parts of the dry north.

Migration

Migration is movement from one place to another. Push factors drive people away: unemployment, conflict, drought. Pull factors attract them: jobs, schools, safety.

Effects

Migration can provide labour and remittances but can also strain housing, services and infrastructure in receiving areas, while losing skilled workers from source areas.

Calculate density

Population: 1 000 000. Area: 5 000 km².

Density = 1 000 000 ÷ 5 000 = 200 people per km².

Tip Rapid population growth does not automatically cause poverty, but it makes investment in schools, health and jobs more urgent.

Practice

Calculate density: population 600 000, area 3 000 km².
Name two push and two pull factors.
Describe one positive and one negative effect of rural-urban migration.

Recap

Population density measures crowding. Migration is driven by push and pull factors and has mixed effects.
