Population divided by area does not reveal exactly where people live within that area.
Migration has varied causes
Economic opportunities, family links, conflict, environment and policy may interact.
Examples and reasoning
A model region has 2400 residents in 12 km². Find average population density in residents/km².
2400 ÷ 12 = 200
200
