This article discusses the effects of and reactions to the free movement of labor within the 6 states of the European Community (EEC) since its beginning in 1968. A summary of the movements shows that 1) large flows from "underdeveloped areas" within the community to the "more developed ones" have not occurred, 2) an increase in the exchanges of nationals within the EEC and therefore also between highly developed areas has occurred, and 2) strong indications exist that the extent of this exchange is primarily linked to demand and to the economic climate. Those who had forecast doom had made the following errors: 1) many based their forecasts on fears and selective perceptions linked to them, 2), many were insufficiently aware of the rules governing free movement and the way they operate, and 3) they had too little knowledge of the situation in the areas assumed to provide the push. 3 factors important for forecasting migration are 1) studies of migration almost always use only 1 level of analysis, 2) one must take into account the role of national governments, and of legislation and regulations affecting migration and migrants, and 3) prognoses should be made for each category of migrants separately. The authors formulate assumptions on both the macro and the micro level for each category of migrants: 1) migration of individual workers will be very dependent upon changes in the economic situation; 2) an increase in movements of staff within international business organizations will occur 3) migration of enterpreneurs will increase once the legal and practical impediments disappear, 4) student migration and that of pensioners and persons with private incomes will increase if practical and legal impediments are removed, 5) the European Community does not and will not recognize the existence of refugees who are nationals of 1 of its member states, and 6) illegal migrants will be few. Predicted migration of non-community nationals to European Community member states includes 1) immigration of skilled migrant workers, in the event of an economic boom, is more likely than immigration of unskilled workers; 2) the number of people claiming refugee status and asylum will grow, if there are no opportunities available for a refugee elsewhere; and 3) developments in the labor market influence both the choice of potential illegal immigrants and the severity of any policy of prosecuting employers of illegal labor.
