During which stage of spatial diffusion does the process slow to a stop?

The concept of spatial diffusion is integral to understanding how ideas, technologies, or cultural practices spread across different regions. The stage at which the process slows to a stop is known as saturation. During the saturation stage, the market or area has reached a point where the diffusion has maximized and further spread is limited. This occurs because most potential adopters have already accepted the innovation, and there are fewer individuals or places left to influence.

At this point, the rate of adoption slows significantly as the population has predominantly integrated the innovation into their lifestyles, leading to a plateau in growth. Understanding this stage is essential for recognizing the lifecycle of innovations and how cultural or technological changes can happen across different geographical areas.
