- most migration is step by step
- cities increase in population due to migration, not natural increase
- the major reason for migration is economic
- males are more likely to move internationally
- migration increases as industry and economy develops

what is the gravity model
the theory that spatial interaction is directly related to the populations and inversely related to the distance between them
what are push factors
conditions and perceptions that help a migrant decide to leave a place
what are pull factors
circumstances that effectively attract the migrant to certain locales to other places, the decision of where to go
what is distance decay
interaction decreases as distance increases –> migrants are likely to feel much less certain about distant destinations than about nearer ones
