The medium-size towns in the conurbations of the GDR represent the secondary knots in the settlement network and concentration points of population, industry and infrastructure. They are political, economic and intellectual-cultural centres
and therefore have significant caretaking and supplying functions for a certain fringe area. Importance and features of the secondary knots depend on their location within the settlement network and the size of the population. While the small medium-size towns
are located in the agglomeration and the fringe area, the large medium-size towns are usually placed in the distinctly marginal positions. The secondary knots are at present the focal points in the urbanization process. The medium-size towns provide good
conditions for their further development, due to their economic role, their potential labour force, their favourable infrastructural features and their resources, combined with advantageous relations of town location and fringe area.
The fill-in concept was devised to describe the process of migration from rural areas to small towns in Latin America. The paper argues that the concept is theoretically unsound and is normally indistinguishable as a pattern from direct and/or step
movements. Indeed, the patterns of migration to and from small towns are far more complex than those suggested by the fill-in concept. The limited evidence available suggests that return migration is considerable and that the selectivity of in-migrants
reduces the debilitative effects of out-migration on small town populations.
Migration is often used as one of the possible criteria in determining a service area by means of migration-distance models. In this article the zone of influence of a town will not be considered a disturbing factor but will on the contrary
