Christaller's Theorem

Christaller's Theorem, developed by Walter Christaller in the 1930s, explains how cities and towns are organized in relation to one another. It suggests that settlements tend to be arranged in a hierarchical pattern, where larger cities provide services for a wider area and smaller towns serve local needs. This creates a system where people travel farther for specialized services found in larger cities, while smaller towns offer everyday goods. Essentially, it helps us understand the spatial distribution of human communities and how they interact based on the services they provide.
