People cluster where there's water, work, and safety, and pull up roots when war, drought, or opportunity calls. Population and migration maps trace where humans settle and why they pick up and move.
People are not spread evenly
Population density measures how many people live in a given area. People cluster where land, water, and jobs support them — river valleys, coasts, and cities. Migration is the movement of people; it's shaped by push factors (war, drought, poverty) that drive people away and pull factors (jobs, safety, family) that draw them somewhere new.
For the first time in history, more than half the world lives in cities. People migrate from rural areas to cities seeking work and services — a global trend called urbanization.
Drought pushing farmers off their land (push) plus factory jobs in a city (pull) together drive rural-to-urban migration.
- A family leaves a region because of a long war.
- Decide whether the war is a push or a pull factor.
- Name one pull factor that might draw them to a new city.
What you should see: War is a push factor driving them away; a pull factor could be job opportunities or safety in the destination city.
