Locations or places about which an individual has knowledge even without visiting all of them; includes activity space and additional areas newly encountered or about which one acquires information
The process by which migration movements from a common home area to a specific destination are sustained by links of friendship or kinship between first movers and later followers.
The tendency for migration to flow between areas that are socially and economically allied by past migration patterns, by economic and trade connections, or by some other affinity.

The declining intensity of any activity, process or function with increasing distance from its point of origin.
friction of distance
A measure of the retarding or restricting effect of distance on spatial interaction. Generally, the greater the distance, the greater the "friction" and the less the interaction or exchange, or the greater the cost of achieving the exchange.
A mathematical prediction of the interaction between two bodies as a function of their size and of the distance separating them. Henry C. Carey adapted Newton's formulation to demonstrate the theoretical interaction between two cities.
The concept that closer opportunities will materially reduce the attractiveness of interaction with more distant - even slightly better - alternatives; a closer alternative source of supply between a demand point and the original source of supply.
The permanent (or relatively permanent) relocation of an individual or group to a new, usually distant, place of residence and employment.
the movement of people in a population, as from place to place, from job to job, or from one social class or level to another.

A measurement of the total interaction opportunities available under gravity model assumptions to a center in a multi-center system.
Characteristics of a locale that act as attractive forces, drawing migrants from other regions.
Unfavorable characteristics of a locale that contribute to the dissatisfaction of its residents and impel their emigration.
Also know as the law of retail gravitation; the proposition by William J. Reilly that the breaking point or boundary marking the outer edge of either of two cities' trade area is located by the expression...
return of migrants to the regions from which they earlier emigrated
A diagram of the volume of space and the length of time within which our activities are confined by constraints of our bodily needs (eating, resting) and the means of mobility at our command.
The movement ( e.g. of people, goods, information ) between different places; an indication of interdependence between different geographic locations or areas.
The process by which individuals evaluate the alternative locations to which they might move.
A migration in which an eventual long-distance relocation is undertaken in stages as, for example, from farm to village to small town to city.
An individual or group attempt to identify and establish control over a clearly defined territory considered partially or wholly an exclusive domain; the behavior associated with the defense of the home territory.
