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.
In other words, this diffusion occurs when the trend spreads to a new location and changes in its new location or context. Contagious diffusion is a type of diffusion where a trend or idea spreads based on person-to-person contact within a given population. The main characteristic of contagious diffusion is that it spreads from person to person. This is a rapid spread, like a contagious disease or a forest fire.
It's no coincidence that something that spreads quickly and widely on social media is deemed "going viral. Hierarchical diffusion follows a chain of command, something you see in business, government, and the military.
The CEO of a company or the leader of a government body generally knows information before it is disseminated among a wider employee base or the general public. Fads and trends that start with one community before spreading to the wider public can also be hierarchical. Hip-hop music springing up in urban centers is one example. Slang expressions that owe their genesis to one particular age group before being more widely adopted—and perhaps eventually making it into the dictionary—would be another.
In stimulus diffusion, a trend catches on but is changed as it is adopted by different groups, such as when a certain religion is adopted by a population but the practices are blended with the customs of the existing culture. When enslaved people brought Voodoo, which has its origins in African tradition, to America, it was blended with Christianity, incorporating many of that religion's important saints.
Stimulus diffusion can also apply to the more mundane as well. Another example would be the menus of McDonald's restaurants from around the world. While they resemble the original, many have been adapted to suit local tastes and regional religious food doctrines. In relocation diffusion, that which moves leaves behind its point of origin but rather than simply being changed along the way or changing when it arrives at a new destination, it may also change points along the journey as well as the eventual destination, simply by being introduced there.
In nature, relocation diffusion can be illustrated by the movement of air masses that spawn storms as they spread across a landscape. When people immigrate from country to country—or simply move from the country to the city—they often share cultural traditions and practices with their new community when they arrive. These traditions may even be adopted by their new neighbors.
This is especially true of food traditions. Relocation diffusion can occur in the business community as well. When new employees come to a company with good ideas from their previous workplaces, smart employers will recognize the found knowledge as an opportunity and leverage it improve their own companies.

Cultural Diffusion The definition of cultural diffusion noun is the geographical and social spread of the different aspects of one more cultures to different ethnicities, religions, nationalities, regions, etc.
Cultural diffusion is about the spreading of culture over time. There are many types of cultural diffusion, and in this guide we will go over the types and provide examples. The following study guides in this unit series go into additional examples of cultural diffusion in specific historic and modern contexts. Relocation Diffusion occurs when people move from their original location to another and bring their innovations with them.
Immigration from country to country, city to city, etc. As they relocate to a new location, they bring their ideas, cultural tradition such as food, music, and more. As masses of individuals immigrate to a new environment, they bring along their cultural connections, influencing others in the new environments. Relocation diffusion can also be forced rather than chosen. Many cultural components of Southern US architecture, cuisine, and music have African and Caribbean origins due to the forced relocation and enslavement of African people during the trans-atlantic slave trade.
