Relocation diffusion moves with migrating people.
Expansion diffusion
- Expansion diffusion 扩展扩散 spreads outward while staying strong at the source. Three types:
- Contagious — person-to-person to nearby people (a viral video).
- Hierarchical — from big, important places first (a trend from major cities); stimulus — the idea spreads even as the form changes (a chain adapting its menu).

Relocation = moved with people; contagious = nearby; stimulus = idea spreads, form changes.
The key split: in relocation diffusion the people move (and carry the trait); in expansion diffusion the people mostly stay and the trait spreads outward from a source that keeps it. Ask: did the carriers migrate, or did the idea jump while they stayed put?
A viral dance spreading through a school is contagious (person to person, nearby). A fashion appearing in world capitals before small towns is hierarchical (big places first). Immigrants bringing a festival to a new country is relocation (it moved with them).
Diffusion spreads a trait from its hearth. Relocation diffusion moves with migrating people; expansion diffusion spreads outward while staying strong at the source, in three forms: contagious (nearby), hierarchical (big places first), and stimulus (idea spreads, form changes).
