PRIMATE CITIES
• In less developed countries/regions the largest city is overly large. The pattern of settlements is such that the largest settlement has more than twice as many people as the second largest settlement.

Why do we care?- Interesting math!
- Countries that have good rank-size distribution improve the quality of life of their citizens. A regular hierarchy (USA) indicates that a society is wealthy enough to provide services for its people.
- Absence of rank-size means people may struggle to access large urban settlements, thus high level services like hospitals.
