Expansion diffusion occurs when a trend or idea spreads from its original source, outwards. It rapidly spreads through a population, and the amount of those influenced by the trend grows continuously larger. There are three types of expansion diffusion: stimulus diffusion, hierarchical diffusion, and contagious diffusion.
This is the type of diffusion that occurs when a concept or trend spreads from a place or person of power or high susceptibility to another in hierarchical order. In other words, the trend first spreads among influential or powerful individuals in society and then spreads to other individuals. For instance, think of a chain of command in a business.
Fashion trends and music spreading first in urban areas or among a certain class of people before gaining popularity in the wider public is an example of hierarchical diffusion. In stimulus diffusion, a trend or innovative idea diffuses from its hearth to outward locations, but the trend is changed by its new adopters.
