Distance+Decay

Population and Migration

"When considering pull factors, distance decay comes into play. Prospective migrants are likely to have more complete perceptions of nearer places than of farther ones, whcih confirms the notion that the intensity of human activity, process, or function declines as distance from its source increases. " Deblij, page 76 What does this mean? - Migrants are less likely to move to farther places than closer ones. ** Why? ** They feel less certain and know less about the distance places. - Migrants sometimes go distances shorter than originally planned.

- Step migration- migration streams that consist of a series of stages. Each stage has a set of pull factors that come in play.
