Rapid technological developments in the field of information, computers and communications are leading to significant structural changes in the economies of Member countries. Flows of computerised data and information are an important consequence of technological advances and are playing an increasing role in national economies. With the growing economic interdependence of Member countries, these flows acquire an international dimension, known as Transborder Data Flows. It is therefore appropriate for the OECD to pay attention to policy issues connected with these transborder data flows. This Declaration was adopted by the Governments of OECD Member countries on 11th April 1985.
