migration according to demographers: a component of change that, together with natural increase, determines the magnitude and rate of population growth
Sociological perspective: migration is significant because residential relocation brings about new activities and terminates old ones, with subsequent social and economic impacts at both the destination and the origin
migration is usually a group activity that can include family members, neighbors, friends, and members of particular religions
migration may be temporary, long-term or permanent
involuntary: "forced", if decision to migrate is made by others, contrary to the will of the immigrants; or if it is the result of external forces such as natural disasters

in-migration: movement of people out of the territory occupied by a specific population or subpopulation for the purpose of residential relocation
size of in-migration flows,"I", measured by counting the individuals who newly enter a geographic region for the purpose of changing residence, during a given interval of time
out-migration: movement of people out of the territory occupied by a specific population or subpopulation for the purpose of residential relocation
size of out-migration flows, or “O,” is measured by counting the number of individuals who depart from a region during a year or other interval
net-migration: difference between the number of in-migrations and the number of out-migrations experienced by a population during a given interval of time
gross migration: sum total of all in-migrations and out-migrations experienced by a population during a given interval of time, also known as the volume of migration
in-migration rate: (I/P) x 1,000
out-migration rate: (O/P) x 1,000
net migration rate: [(I-O)/P] x 1,000
gross migration rate: [(I+O)/P] x 1,000
international migration: movement of people between specific territorially based subpopulations of a larger, general population
intracity move: if the origin and destination of such a movement is within city boundaries, for instance, between neighborhoods
