The paper reports on a study dealing with emergent regionalization among veteran settlements in Israel. Regional organization is approached in a functional way, as a social system in a process of change and is considered in its micro and macro aspects. The focus of the analysis is threefold: the function of the region as a mechanism of developmental change in terms of social integration, increased participation and redistribution, and improved mobilization; the factors which influence the process of regionalization, in its initial emergence, and in its sustained functioning; and the relationship between different regional organization and social structure and institutions.
