i. Interaction depends on separation between distances. Places that are further apart have less interaction. The model of social interaction is analogous to the physical pull between to physical objects. Measure the mass of places- certain places pull more interaction, distance being equal. Population size in a city can quantify pull. |

It generally takes the form of a square grid of 25 cells, with each cell being assigned a probability of being contacted. The possibility of contact is very high in the central cells from which the diffusion takes place, becoming markedly less so with distance from the centre, that is, there is a distance decay effect. |
