The structure of the migration process: findings from a growth point in mid-Wales.

As an aid to understanding the pattern of population movement to a small town in Mid-Wales currently being expanded by a Development Corporation, a conceptual model is introduced of the decision-making process in migration. Emphasis is given to the developmental or biographical analysis of action, with a stayer-mover option at each major stage of development. The model provides a framework for the description and interpretation of migration data derived from an interview survey of incoming Development Corporation tenants. THIS paper arises out of an attempt to understand the pattern of migration in a specialized context: that of population growth promoted by a Development Corporation in a small and fairly remote town, Newtown, in Mid-Wales. There are no prototypes of comparable urban develop- ment in Britain. The other new towns have much larger target populations and are all located within or near densely peopled regions. There are some parallels with several expanded towns in
