Topic 8 What is the Migration Transition? The permanent movement of people from one place to another; Usually in response to resource scarcity, typically caused by population growth, in the area of origin relative to perceived resources in the destination area; Now closely related to the urban transition because most migrants are moving to urban areas, no matter where they are from. Defining Migration Permanent change of residence (residential mobility), moving a great enough distance that all activities are transferred from one place to another. International migrants move between countries (either legally or without documentation). Internal migrants move within national boundaries (usually without constraint, but not always). Measuring Migration “Permanence” usually means that you’ve been gone at least one year from the old place. “Distance moved” in the U.S.--the Census Bureau defines a migrant as a person who has moved to a different county within the U.S. But, from the standpoint of a local school district, for example, a migrant would be someone moving into or out of the school district’s boundaries. Stocks Versus Flows The migration transition involves a process and a transformation. The process is that people move from one place to another and this represents the migration flow . The transformation is that the migrant stock changes as people move into and out of a given place. Migration Indices crude or gross rate of out-migration ( OMigR ): crude or gross rate of in-migration ( IMigR ): crude net migration rate ( CNMigR ): Why Do People Migrate?
Push–pull theory People move because they are pushed out of their former location, or because they have been pulled someplace that seems more attractive than where they are. Implementing strategy A goal (education, a better job, a nicer house, a more pleasant environment, and so on) might be attained by moving. Key Generalizations About Migration: 1. Migration is selective: only a selected portion of the population migrates.
