Answer:
migration
Migration in geography usually refers to the movement of humans from one place to another. It occurs when the perceived interaction of Push and Pull factors overcome the friction of moving.
Push factors: elements of the origin that are perceived negatively leading to a desire to leave.
Pull factors: elements of the destination that are perceived positively leading to place-attraction.
Friction of Moving: costs in time, finance and emotions in leaving one location and moving to another. The strength of the Pull and/or Push factors need to overcome these costs to cause potential migrants to turn that into an actual relocation.
Perception: how a geographical feature may be received be each individual. A quiet coastal resort may be seen as ‘boring’ by a teenager (and the ‘quietness’ a Push factor), but attractive to a retired couple (so a Pull factor). This may result in coastal resorts seeing a net out-migration of young people and net in-migration of the recently retired.
Net Migration: the sum change in migrant numbers between those coming into an area (in-migrants) and those leaving (out-migrants). If migration crosses international borders a person is an Emigrant from the country they leave and an Immigrant to the country they are going to.
