Distance Decay Function

The Distance Decay Function describes how the influence or interaction between two places decreases as the distance between them increases. In simpler terms, the farther two locations are from each other, the less likely people are to connect, communicate, or travel between them. This concept is commonly seen in areas like trade, migration, and social interactions, where nearby places tend to have stronger relationships compared to distant ones. Essentially, as you move further away from a location, the impact or likelihood of interaction diminishes.
