Distance Decay

 

(Shown on the top left)

 

• Distance decay- the effects that distance has on interactions.

• Generally the larger the distance, the less interactions that there are.

• Distance decay is a sort of opposition to globalization, because globalization has made places become closer together despite the distances. (Space-time compression also) 

• Distance decay relates to many other topics in geography, such as diffusion, like the contagious diffusion of ideas and innovations.

•  For the laws of migration and the gravity model, distance decay plays a major role because most migrants move only short distances, and over a large distance, the interactions become less and less.​

1. Space-time compression is not the same as distance decay.

2. People can communicate with technology like phones and travel farther distances in less time and quicker. 

3. So, with this, diffusion kind of depends more on conncetions between people and places.

4. Unlike distance decay, where it spreads just to more just nearby areas mostly.
