For the time being, at least, survey data is relevant to the study of regional integration chiefly insofar as it gives an indication of the influence of the public (and various elite groups) on the decisions of the respective national governments—and vice versa. As integration progresses in given regions our focus may change, and we may become primarily interested in the degree to which given groups direct support or demands toward supranational institutions. But for the present the basic question seems to be: To what extent do public preferences constitute an effective influence on a given set of national decisionmakers, encouraging them to make decisions which increase (or diminish) regional integration?
